Element: ariaColCount property
The ariaColCount
property of the Element
interface reflects the value of the aria-colcount
attribute, which defines the number of columns in a table, grid, or treegrid.
Value
A string.
Examples
In this example the aria-colcount
attribute on the element with an ID of semantic-table
is set to "2". Using ariaColCount
we update the value to "3".
