recexpr is not inherently anchored to beginning of line.
If your data really is that simple, a recexpr of
recexpr >><td>=!</td>*</td>
field Col varchar 2
will grab each table column as a record and the column data will be
placed into the $Col variable.
If you still have problems, please be more specific about what you're
actually doing. Don't forget to <loop> over $Col if you're trying
to use it after <timport></timport> instead of between.
