Regular Table Column Width*
*Not sure how to change the width, but works if you make sure to wrap text header and change its height.

from Spotfire.Dxp.Application.Visuals import TablePlot
tablePlot = tp.As[TablePlot]()
tablePlot.WrapHeaderText = True
#toggle height between 1 and 2
tablePlot.HeaderHeight = 1 if tablePlot.HeaderHeight==2 else 2
