Re: Guidelines for nested data tables?

Well a few questions:
Do the child data rows produced on expanding a parent row share the
same column headings as the parent row?
Is there a mechanism (markup) by which you are conveying the relation
between parent row and child row?
Often in such a case, the parent table appears to be used partly as a
data table and partly as a layout table. This happens if parent data
rows and child data rows have need for different column headers. Are
there some data rows to which certain column headers do not apply?
The need for a blank TR is also perhaps an indication of this.
If the design becomes complex, one may need to use header-id method of
relating data cells with header cells. That is error prone and not a
task one would like to do.
