HTML - scope Attribute

HTML scope is an HTML attribute that is used to define the header cell. It is used for the header row, column, colgroup, or rowgroup.

The <th> element specifies a cell as the header of a group of table cells. The scope and headers attributes specify the nature of this group.

Note:This attribute is used by screen readers but has no visible effect on the browser.

If the scope attribute is not defined, then browsers automatically select the group of cells to which the header cell applies.

Syntax

<th scope=" col | row | colgroup | rowgroup " >

row: The header relates to all cells of the row it belongs to.
col: The header relates to all cells of the column it belongs to.
rowgroup: The header belongs to a rowgroup and relates to all of its cells.
colgroup: The header belongs to a colgroup and relates to all its cells.
