Hi,

this behavior if counter-intuitive, and may be boggus (as it does not
follow the content of the help file).
If you use widget_control this way, you should select the cells to be
updated firts (add some row, select them, then set the value).

However, if you do:
data = [d0, d1 , d2, d3,d0, d1, d2, d3,d0, d1, d2, d3,d0, d1, d2,d3]
WIDGET_CONTROL, table1, set_value=data, Table_YSize = n_elements(data),
then you will see everything...
