--- layout: docs title: Tables description: Documentation and examples for opt-in styling of tables (given their prevalent use in JavaScript plugins) with Bootstrap. group: content toc: true --- ## Overview Due to the widespread use of `` elements across third-party widgets like calendars and date pickers, Bootstrap's tables are **opt-in**. Add the base class `.table` to any `
`, 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 >}}
{{< table.inline >}} {{- range (index $.Site.Data "theme-colors") }} {{- end -}} {{< /table.inline >}}

``` ## How do the variants and accented tables work? For the accented tables ([striped rows](#striped-rows), [striped columns](#striped-columns), [hoverable rows](#hoverable-rows), and [active tables](#active-tables)), we used some techniques to make these effects work for all our [table variants](#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]({{< docsref "/utilities/borders#border-color" >}}) 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—``, ``, and ``—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 >}}

{{< /example >}} ## Vertical alignment Table cells of `` are always vertical aligned to the bottom. Table cells in `` inherit their alignment from `` and are aligned to the top by default. Use the [vertical align]({{< docsref "/utilities/vertical-align" >}}) classes to re-align where needed.

``` ## 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 `td`s and `th`s 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 `td`s and `th`s of the `.table`, but none of any potential nested tables. Note that if you add ``s as direct children of a table, those `` will be wrapped in a `` 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 ``s appear light or dark gray.

{{< /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.

``` ### 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") }}
