Tree Table

Use up to three levels of tree-style grouping for data that requires a visual hierarchy.

To display more than three levels, coordinate with a System team member to extend the table’s display capabilities.
Note: Tree tables do not inherently meet accessibility requirements. Avoiding tree tables ensures the best experience for users employing a screen reader. If requirements call for use of a tree table, use aria-label attributes on the <th> elements to describe the parent/child relationship for screen readers, for example:

<tr>
    <th aria-label="Orange, has one nested child, tangerine" class="mds-data-table__cell" scope="row">Orange</th>
    <td>...</td>
    <td>...</td>
</tr>
<tr>
    <th aria-label="Tangerine, child of orange" class="mds-data-table__cell mds-data-table__cell--child" scope="row">Tangerine</th>
    <td>...</td>
    <td>...</td>
</tr>

Highlight the selected/sorted column with a caret and rule by adding a mds-data-table__header-cell-inner--selected-ascending or mds-data-table__header-cell-inner--selected-descending class.

Sizing

Sizing affects text size and internal padding. The default size is medium, and you can use modifier classes to make the data table smaller (mds-data-table--small) or larger (mds-data-table--large).

Guidelines

Use When

Displaying data in a tabular format.
Displaying one or more columns of data.

Visual Language

Always left align alphabetic columns.
Always right align numeric columns.

Always bottom align column headers to ensure consistent spacing between headers of varying length and the first row in the table.

Always top align cell content to ensure a row of columns with variable-length content have a consistent baseline.

Place the primary identifying column, often “Name”, leftmost in the table.

Do use an em-dash (—) in null data cells.

Don‘t use any other dash, like hyphen, en-dash, or minus.

Do use the minus sign (−) to represent negative values.

Don‘t use any other dash, like hyphen or em-dash.

Editorial

Try for clear, short column headers.
Preferably one line, but two is OK.
Never spell out numbers.
Put currency and other symbols inside parentheses when technically possible, i.e., “USD ($)”.

Accessibility

Always use a <caption> to describe table contents.
Always place the <caption> as the first DOM node after the <table> element. By default, our .mds-data-table__caption element is hidden. The purpose of the <caption> element is to enable a better experience for people using screen readers.
Always include table header labels.
Always use <th> tags for cells containing header labels.
Refrain from setting fixed pixel widths on tables. Instead, let the browser size the table.
Avoid setting heights on table cells. They need to be able to expand to fit the contents within them.
Never put a pixel width on a cell. Instead, use a percentage.
If you have multiple tables in succession, do not combine all the data into the same table. Start a new <table> set to clearly define separation between data sets.
Never use tables for layout purposes.
Use ARIA roles (grid, row, gridcell) if Data Table contains interactive actions such as buttons.
Always add role="button" to identify column header as a clickable action for sorting. Include tabindex="1" to allow keyboard tabbing.
Add aria-sort (ascending, descending, none are possible values).
Add aria-readonly="false" if table is editable otherwise set true.
