Hi rolf,

Your suggestions worked fine, see the picture (I'm doing my drug 
prescribing section at the moment)

Using  the grids richtext property and the table.font.width to keep 
track of the widest of each column makes it easy to set the column 
widths, and row heights as per the picture.
It would also be easy to put in more sophisticated handling of anomalous 
widths to keep a very long column text from pushing out the width to an 
unreasonable size compared to the general column width.

thanks again

Richard
