I don't know why this doesn't work, but perhaps you need to set the
column as usable and define the custom draw procedure first, before
setting the item style? This is what I do:
width = TblGetColumnWidth(table,0) ;
height = width + 1 ;
for ( column=0 ; column<nColumns ; column++ )
{
TblSetCustomDrawProcedure(table,column,DrawChartCell) ;
TblSetColumnUsable(table,column,true) ;
for ( row=0 ; row<nRows ; row++ )
{
TblSetItemStyle(table,row,column,customTableItem) ;
TblSetItemInt(table,row,column,(row+offset)*nColumns+column) ;
TblSetRowHeight(table,row,height) ;
}
}
TblMarkTableInvalid(table) ;
and all I can say is, it works for me. :/ This is CW R5, btw.
