HTMLTableCellElement: scope property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The scope property of the HTMLTableCellElement interface
indicates the scope of a <th> cell.
Header cells can be configured, using the scope attribute, to apply to a specified row or column, or to the not-yet-scoped cells within the current row group (that is, the same ancestor <thead>, <tbody>, or <tfoot> element). If no value is specified for scope, the header is not associated directly with cells in this way. Permitted values for scope are:
Note: This property doesn't have a visual effect in browsers. It adds semantic information to help assistive technology like screen readers to present the table in a more coherent way.
Value
One of the following values:
col-
The header cell applies to the following cells in the same column (or columns, if
colspanis used as well), until either the end of the column or another<th>in the column establishes a new scope. colgroup-
The header cell applies to all cells in the current column group that do not already have a scope applied to them. This value is only allowed if the cell is in a column group.
row-
The header cell applies to the following cells in the same row (or rows, if
rowspanis used as well), until either the end of the row or another<th>in the same row establishes a new scope. rowgroup-
The header cell applies to all cells in the current row group that do not already have a scope applied to them. This value is only allowed if the cell is in a row group.
- The empty string (
"") -
The header cell has no predefined scope; the user agent will establish the scope based on contextual clues.
Examples
This example adds a scope label to all the th numbers of the thead.
