In tbl(7) -T html output,

span cells horizontally and vertically as requested by the layout.
Does not handle spans requested in the data section yet.

To be able to do this, record the number of rows spanned
in the first data cell (struct tbl_dat) of a vertical span.

Missing feature reported by Pali dot Rohar at gmail dot com.
