I have a table with the following spec at the top:
Intended to have left-horizontally aligned cols 1, 2 and last, and centred for the rest.
Then, some rows have the following:
To get a 3-row span in the first column.
The result is nearly correct, except that column centering doesn't work properly in the subsequent rows of the groups starting with a row-span marker shown above.
It seems to me as if cell-counting is being used to determine what column the formatting is output for, without taking account of the row-spanning. Or is there just a trick to make this work that I can't see in the documentation?
