Tables

Overview

Due to the widespread use of <table> elements across third-party widgets like calendars and date pickers, Boosted’s tables are opt-in. Add the base class .table to any <table>, then extend with our optional modifier classes or custom styles. All table styles are not inherited in Boosted, meaning any nested tables can be styled independent from the parent.

Using the most basic table markup, here’s how .table-based tables look in Boosted.

<table class="table">
  <caption class="visually-hidden">Boosted tables basic look</caption>
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

Accessibility

To make a table accessible, you should respect these three main rules:

• If the table is an important one, add a role="region" attribute to help screen readers.
• add a scope="col" or scope="row" attribute to the tags when needed to make the content of table readable by screen readers.
• add a <caption> on each table. If the table doesn’t have a caption or if the caption is not enough informative to describe the table, add an aria-label attribute to describe the table content. The aria-label should match the following pattern: aria-label="Description of table data - Description of table metadata (e.g.: table with one level of column header)". The metadata is mandatory for complex tables.

Accented tables

Striped rows

Use .table-striped to add zebra-striping to any table row within the <tbody>.

<table class="table table-striped">
  ...
</table>

Striped columns

Use .table-striped-columns to add zebra-striping to any table column.

<table class="table table-striped-columns">
  ...
</table>

<table class="table table-dark table-striped">
  ...
</table>

<table class="table table-dark table-striped-columns">
  ...
</table>

<table class="table table-success table-striped">
  ...
</table>

<table class="table table-success table-striped-columns">
  ...
</table>

Hoverable rows

Add .table-hover to enable a hover state on table rows within a <tbody>.

<table class="table table-hover">
  ...
</table>

<table class="table table-dark table-hover">
  ...
</table>

These hoverable rows can also be combined with the striped rows variant:

<table class="table table-striped table-hover">
  ...
</table>

<table class="table table-dark table-striped table-hover">
  ...
</table>

Active tables

Highlight a table row or cell by adding a .table-active class.

<table class="table">
  ...
  <thead>
    ...
  </thead>
  <tbody>
    <tr class="table-active">
      ...
    </tr>
    <tr>
      ...
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2" class="table-active">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

<table class="table table-dark">
  ...
  <thead>
    ...
  </thead>
  <tbody>
    <tr class="table-active">
      ...
    </tr>
    <tr>
      ...
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2" class="table-active">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

How do the variants and accented tables work?

For the accented tables (striped rows, striped columns, hoverable rows and active tables), we used some techniques to make these effects work for all our table variants:

• We start by setting the background of a table cell with the --bs-table-bg custom property. All table variants then set that custom property to colorize the table cells. This way, we don’t get into trouble if semi-transparent colors are used as table backgrounds.
• Then we add an inset box shadow on the table cells with box-shadow: inset 0 0 0 9999px var(--bs-table-bg-state, var(--bs-table-bg-type, var(--bs-table-accent-bg))); to layer on top of any specified background-color. It uses custom cascade to override the box-shadow, regardless the CSS specificity. Because we use a huge spread and no blur, the color will be monotone. Since --bs-table-accent-bg is set to transparent by default, we don’t have a default box shadow.
• When either .table-striped, .table-striped-columns, .table-hover or .table-active classes are added, either --bs-table-bg-type or --bs-table-bg-state (by default set to initial) are set to a semitransparent color (--bs-table-striped-bg, --bs-table-active-bg or --bs-table-hover-bg) to colorize the background and override default --bs-table-accent-bg.
• For each table variant, we generate a --bs-table-accent-bg color with the highest contrast depending on that color. For example, the accent color for .table-dark has a lighter accent color.
• Text and border colors are generated the same way, and their colors are inherited by default.

Behind the scenes it looks like this:

@mixin table-variant($state, $background) {
  .table-#{$state} {
    $color: color-contrast(opaque($body-bg, $background));
    $hover-bg: mix($color, $background, percentage($table-variant-hover-bg-factor));// Boosted mod
    $striped-bg: mix($color, $background, percentage($table-variant-striped-bg-factor)); // Boosted mod
    $active-bg: mix($color, $background, percentage($table-variant-active-bg-factor)); // Boosted mod
    $table-border-color: mix($color, $background, percentage($table-border-factor));

    --#{$prefix}table-color: #{$color};
    --#{$prefix}table-bg: #{$background};
    --#{$prefix}table-border-color: #{$table-border-color};
    --#{$prefix}table-striped-bg: #{$striped-bg};
    --#{$prefix}table-striped-color: #{color-contrast($striped-bg)};
    --#{$prefix}table-active-bg: #{$active-bg};
    --#{$prefix}table-active-color: #{color-contrast($active-bg)};
    --#{$prefix}table-hover-bg: #{$hover-bg};
    --#{$prefix}table-hover-color: #{color-contrast($hover-bg)};

    color: var(--#{$prefix}table-color);
    border-color: var(--#{$prefix}table-border-color);
  }
}

Small tables

Add .table-sm to make any .table more compact by cutting all cell padding in half.

<table class="table table-sm">
  ...
</table>

<table class="table table-dark table-sm">
  ...
</table>

Table group dividers

Add a thicker border, darker between table groups—<thead>, <tbody>, and <tfoot>—with .table-group-divider. Customize the color by changing the border-top-color (which we don’t currently provide a utility class for at this time).

<table class="table">
  <caption class="visually-hidden">Boosted group divided table</caption>
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody class="table-group-divider">
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

Vertical alignment

Table cells of <thead> are always vertical aligned to the bottom. Table cells in <tbody> inherit their alignment from <table> and are aligned to the top by default. Use the vertical align classes to re-align where needed.

<div class="table-responsive">
  <table class="table align-middle">
    ...
    <thead>
      <tr>
        ...
      </tr>
    </thead>
    <tbody>
      <tr>
        ...
      </tr>
      <tr class="align-bottom">
        ...
      </tr>
      <tr>
        <td>...</td>
        <td>...</td>
        <td class="align-top">This cell is aligned to the top.</td>
        <td>...</td>
      </tr>
    </tbody>
  </table>
</div>

Nesting

Border styles, active styles, and table variants are not inherited by nested tables.

<table class="table table-striped table-bordered">
  ...
  <thead>
    ...
  </thead>
  <tbody>
    ...
    <tr>
      <td colspan="4">
        <table class="table mb-0">
          ...
        </table>
      </td>
    </tr>
    ...
  </tbody>
</table>

How nesting works

To prevent any styles from leaking to nested tables, we use the child combinator (>) selector in our CSS. Since we need to target all the tds and ths in the thead, tbody, and tfoot, our selector would look pretty long without it. As such, we use the rather odd looking .table > :not(caption) > * > * selector to target all tds and ths of the .table, but none of any potential nested tables.

Note that if you add <tr>s as direct children of a table, those <tr> will be wrapped in a <tbody> by default, thus making our selectors work as intended.

Anatomy

Captions

A <caption> functions like a heading for a table. It helps users with screen readers to find a table and understand what it’s about and decide if they want to read it.

<table class="table table-sm">
  <caption>List of users</caption>
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

You can also put the <caption> on the bottom of the table with .caption-bottom.

<table class="table caption-bottom">
  <caption>List of users</caption>
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

Responsive tables

Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a .table with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl|-xxl}.

Always responsive

Across every breakpoint, use .table-responsive for horizontally scrolling tables.

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Breakpoint specific

Use .table-responsive{-sm|-md|-lg|-xl|-xxl} as needed to create responsive tables up to a particular breakpoint. From that breakpoint and up, the table will behave normally and not scroll horizontally.

These tables may appear broken until their responsive styles apply at specific viewport widths.

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

<div class="table-responsive-sm">
  <table class="table">
    ...
  </table>
</div>

<div class="table-responsive-md">
  <table class="table">
    ...
  </table>
</div>

<div class="table-responsive-lg">
  <table class="table">
    ...
  </table>
</div>

<div class="table-responsive-xl">
  <table class="table">
    ...
  </table>
</div>

<div class="table-responsive-xxl">
  <table class="table">
    ...
  </table>
</div>

Rich content tables

Row selection

Add a .form-check div within <th> and <td> to display checkboxes and use the checked attribute, and use .has-checkbox on the table to get correct spacing on the first column.

<div class="table-responsive">
  <table class="table table-sm table-hover has-checkbox">
    ...
    <thead>
      <tr>
        <th scope="col">
          <div class="form-check mb-0">
            <input class="form-check-input" type="checkbox" id="customCheck">
            <label class="form-check-label" for="customCheck">
              <span class="visually-hidden">Select all</span>
            </label>
          </div>
        </th>
        <th scope="col">Column header</th>
        <th scope="col">Column header</th>
        <th scope="col">Column header</th>
        <th scope="col">Column header</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>
          <div class="form-check mb-0">
            <input class="form-check-input" type="checkbox" id="customCheck1">
            <label class="form-check-label" for="customCheck1">
                <span class="visually-hidden">Select first row</span>
            </label>
          </div>
        </td>
        <td>Cell text</td>
        <td>Cell text</td>
        <td>Cell text</td>
        <td>Cell text</td>
      </tr>
      <tr>...</tr>
      <tr class="table-active">
        <td>
          <div class="form-check mb-0">
            <input class="form-check-input" type="checkbox" id="customCheck3" checked>
            <label class="form-check-label" for="customCheck3">
                <span class="visually-hidden">Select third row</span>
            </label>
          </div>
        </td>
        <td>Cell text</td>
        <td>Cell text</td>
        <td>Cell text</td>
        <td>Cell text</td>
      </tr>
      <tr class="table-active">...</tr>
      <tr>...</tr>
      <tr>...</tr>
      <tr>...</tr>
      <tr>...</tr>
    </tbody>
  </table>
</div>

With icons or thumbnails

Use SVG or PNG to display icons or thumbnails in your compact table data cell elements (40px row height). It will automatically add negative margin to ensure vertical alignment (for icons or thumbnails smaller than 2.5rem).
