Copy Command Suggestion

Numerous times it would have been nice if I could just select all of a table's structure or column headings copied it/them.

Unfortunately, the select works for the whole table, but the copy won't copy everything selected; instead, only the cell on which the cursor is resting when clicking "copy" gets copied.

The copy commands are named "Copy selected rows as XYZ". Selected rows do not get copied for you? Here they do.
