Table Heading 1, 2
The Table Heading 1 typecode should be used for any column headers within the table. If the column headings change mid-way through the table, use the Table Heading 2 typecode to denote the second set of headings. Additional table headings may be added by incrementing the number by 1. A table heading is distinct from the enumeration or caption of the whole table.
