Horizontal spanning in tables is accomplished by placing the content to be spanned in a table cell (<oasis:entry>) and using its namest and nameend attributes to indicate the column on which the span should start and the column on which the span should end (inclusive). Both attributes indicate a column by column name (the content of the colname attribute).
The official OASIS Exchange CALS Table Model documentation can be found at http://www.oasis-open.org/specs/a502.htm
|A name||An alphanumeric string, which may begin with either a letter or a number, that acts as a name for referencing the column|
|Restriction: This attribute may be specified if the element is used.|
