Overview#

Due to the widespread use of <table> elements across third-party widgets like calendars and date pickers, Bootstrap'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 Bootstrap, 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 Bootstrap.

{ { < table class="table" simplified="false" }}

Variants#

Use contextual classes to color tables, table rows or individual cells.

{ { < callout info }} Heads up! Because of the more complicated CSS used to generate our table variants, they most likely won't see color mode adaptive styling until v6. { { < /callout }}

{ { < highlight html }}

{ {< table.inline >} } { {- range (index $.Site.Data "theme-colors") } }

...

{ {- end -} } { {< /table.inline >} }

{ {< table.inline >} } { {- range (index $.Site.Data "theme-colors") } }

...

{ {- end -} } { {< /table.inline >} }

{ {< table.inline >} } { {- range (index $.Site.Data "theme-colors") } } ... { {- end -} } { {< /table.inline >} }

{ { < /highlight }}

{ { < callout info }} { { < partial "callouts/warning-color-assistive-technologies.md" }} { { < /callout }}

Accented tables#

Striped rows#

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

{ { < table class="table table-striped" }}

Striped columns#

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

{ { < table class="table table-striped-columns" }}

These classes can also be added to table variants:

{ { < table class="table table-dark table-striped" }}

{ { < table class="table table-dark table-striped-columns" }}

{ { < table class="table table-success table-striped" }}

{ { < table class="table table-success table-striped-columns" }}

Hoverable rows#

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

{ { < table class="table table-hover" }}

{ { < table class="table table-dark table-hover" }}

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

{ { < table class="table table-striped table-hover" }}

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-primary is darker while .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:

{ { < scss-docs name="table-variant" file="scss/mixins/_table-variants.scss" }}

Table borders#

Bordered tables#

Add .table-bordered for borders on all sides of the table and cells.

{ { < table class="table table-bordered" }}

Border color utilities can be added to change colors:

{ { < table class="table table-bordered border-primary" }}

Tables without borders#

Add .table-borderless for a table without borders.

{ { < table class="table table-borderless" }}

{ { < table class="table table-dark table-borderless" }}

Small tables#

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

{ { < table class="table table-sm" }}

{ { < table class="table table-dark table-sm" }}

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).

{ {< example >} }

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

{ {< /example >} }

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#

Table head#

Similar to tables and dark tables, use the modifier classes .table-light or .table-dark to make <thead>s appear light or dark gray.

<table class="table">
  <thead class="table-light">
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

<table class="table">
  <thead class="table-dark">
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

Table foot#

<table class="table">
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
  <tfoot>
    ...
  </tfoot>
</table>

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 top of the table with .caption-top.

{ {< example >} }

List of users

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

{ {< /example >} }

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}.

{ { < callout warning }}

Vertical clipping/truncation#

Responsive tables make use of overflow-y: hidden, which clips off any content that goes beyond the bottom or top edges of the table. In particular, this can clip off dropdown menus and other third-party widgets. { { < /callout }}

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.

{ {< tables.inline >} } { { range $.Site.Data.breakpoints } } { { if not (eq . "xs") } }

{ { end -} } { {- end -} } { {< /tables.inline >} }

{ { < highlight html }} { {< tables.inline >} } { {- range $.Site.Data.breakpoints -} } { {- if not (eq . "xs") } }

{ { end -} } { {- end -} } { {< /tables.inline >} } { { < /highlight }}

CSS#

Sass variables#

{ { < scss-docs name="table-variables" file="scss/_variables.scss" }}

Sass loops#

{ { < scss-docs name="table-loop" file="scss/_variables.scss" }}

Customizing#

• The factor variables ($table-striped-bg-factor, $table-active-bg-factor & $table-hover-bg-factor) are used to determine the contrast in table variants.
• Apart from the light & dark table variants, theme colors are lightened by the $table-bg-scale variable.
