The SCOPE attribute specifies the cells for which the TH element provides header information. SCOPE is a simpler alternative to using HEADERS if the arrangement of header cells is not complex. Possible values are as follows:

  • row, when the TH provides header information for the rest of the row;
  • col, when the TH provides header information for the rest of the column;
  • rowgroup, when the TH gives header information for the rest of the row group (i.e., the remaining cells of the THEAD, TFOOT, or TBODY);
  • colgroup, when the TH gives header information for the rest of the column group (i.e., the remaining cells of the COLGROUP).
