["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Aristide,

Specifying the width does not change anything for you because your table has
columns, and it's the column widths that determine the widths of their
cells.  To change your column width you should use
TableColumn.setWidth(300), or alternatively pack() the column (if you do
this then the width from your MeasureItem callbacks will be used to
determine the column's new size).
