Tables

Bootstrap 5 Tables

Tables allow you to aggregate a huge amount of data and present it in a clear and orderly way. MDB tables provide additional benefits like responsiveness and the possibility of manipulating the table styles.

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 independently from the parent.

Note: If you need more advanced examples and options, see the links below.

Basic example

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

Conveying meaning to assistive technologies:
Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .visually-hidden class.

Striped

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

Group dividers

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

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 the top by default. Use the vertical align classes to re-align where needed.

Heading 1 Heading 2 Heading 3 Heading 4
This cell inherits vertical-align: middle; from the table This cell inherits vertical-align: middle; from the table This cell inherits vertical-align: middle; from the table Nulla vitae elit libero, a pharetra augue. Cras mattis consectetur purus sit amet fermentum. Vestibulum id ligula porta felis euismod semper.

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.

Additional examples

A few practical examples of the use of tables with typical components such as buttons, checkboxes or icons.

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.

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.

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}.

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.

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.

Customizing in Sass

  • 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-level variable.
