If you use a Google Sheet to populate Table Master and the sheet has headings embedded where the heading spans all columns the heading gets populated only to the first column of the table with multiple word wraps.
It would be handy if when a column value exceeds a specified column width that it would span all remaining columns.
Currently the only way to have a heading display is to go back to the original google sheet and split the heading up into multiple columns. The kearning is off but it is better than the way it is currently displayed by default.
