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.
  • Place the primary identifying column, often “Name”, leftmost in the table.
do use an em-dash (—) in null data cells.

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

dont use any other dash, like hyphen, en-dash, or minus.

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

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

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

dont use any other dash, like hyphen or em-dash.

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

Behaviors

  • 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.

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.
