By default, tables in Vanilla use table-layout: fixed.
There are cases where you might want to use table-layout: auto - e.g. in automatically generated tables. To do this, you need to set the $table-layout-fixed variable to true.
Two utility classes are generated to allow overriding if necessary:
u-table-layout--auto sets the table or any descendant tables of the element it's put on to table-layout: auto.u-table-layout--fixed sets the table or any descendant tables of the element it's put on to table-layout: fixed.The table layout utility classes also apply to tables nested inside an element with the utility class.
