char_var. GENERIC= specifies that multiple variables can use
the same column definition. BLANK_DUPS= suppresses the display of the value
in the column if it does not change from one row to the next (and, because
CLASSLEVELS=ON for the table, if no values in preceding columns that are marked
with BLANK_DUPS=ON changes). HEADER= specifies that the header for the column
will be the text of the dynamic variable COLHD, whose value will be set by
the data component.
The STYLE= attribute specifies that the style element for this column
definition is cellcontents.
The END statement ends the definition.
