33.6.6 Capturing
table row and column counts with variables
Two predefined macro variables allow
you to access the numbers of columns and rows in the current table:
<$$_tblcols> Count
of columns in the current table
<$$_tblrows> Count
of rows in the current table
You can use these variables in macro
expressions that manipulate or make use of table properties. For example,
to add a rule above and below each table by placing the rule in an extra
row that spans all columns:
[TableStartMacros]
*=<tr><td colspan="<$$_tblcols>"><hr></td></tr>
[TableEndMacros]
*=<tr><td colspan="<$$_tblcols>"><hr></td></tr>
