Simpletable attribute group

The simpletable attribute group includes several attributes that are defined on the <simpletable> element and <simpletable> specializations. These attributes are not defined for the OASIS exchange table (<table>).

@keycol: Defines the column that contains headings for each row. No value indicates no key column. When present, the numerical value causes the specified column to be treated as a vertical header.
@relcolwidth: Specifies the width of each column in relationship to the width of the other columns. The value is a space separated list of relative column widths; each column width is specified as a positive integer or decimal number followed by an asterisk character.
For example, the value relcolwidth="1* 2* 3*" gives a total of 6 units across three columns. The relative widths are 1/6, 2/6, and 3/6 (16.7%, 33.3%, and 50%). Similarly, the value relcolwidth="90* 150*" causes relative widths of 90/240 and 150/240 (37.5% and 62.5%).
@refcols: The @refcols attribute is currently undefined, and is reserved for future use.
