Many thanks for that, i've now successfully added rows to my
widget_table using insert_rows in the widget_control routine. I would
now like to extend the widget_table in both directions, that is,
extend the number of rows and the number of columns.

As i understand from the IDL help, a widget_table normally has a /
row_major default set, in which case you can extend the number of
rows, but not the number of columns, as this would require a change in
the structure. By the same token, if you manually set /column_major in
widget_table call, you can increase the number of columns, but not the
number of rows. Might there be a smart way of effectively extending
both the rows and columns of a table?

As there must be so many requirements to effectively increase both
dimensions of a table, i cant help thinking there must be a work
around for this problem. A possible idea might be to create some kind
of widget or possibly a table effectively as row_major, then in the
right most column of each element create a column_major table. This
would effectively do what i need to, effectively increasing both
dimensions of a table.

Could anyone offer any solutions?
Any help would be much appreciated, thank you.
