To define widths for columns in table headings, type:

on the a, sectbeg, flt, tab or l statement, or on the individual elements themselves.

colwid=n defines the number of print positions to be allocated to a column. It can appear on a, flt, sectbeg, tab and l statements to define column widths for an axis, table, or group of tables, as well as being used on n, col or val statements to define column widths for individual items.

Any texts which exceed the colwid= column width will be split at blanks, hyphens or slashes, or at the special characters ! and |.

If colwid= is anywhere in a run, it overrides the automatic set-up for the tables or axes to which it refers. If colwid= is at more than one level, the setting at the lowest level overrides those at any higher levels. For example, colwid= on an element overrides colwid on the l statement or higher for that element only. colwid= on an l statement overrides colwid on the a statement for that axis only.
