You can adjust the column widths of the characteristic attribute table of PARTdataManager. For this, lead the mouse over the border between two columns so that the drag point appears. Then set the desired size. After a change of part or executing a search the default size is displayed again.

Perform the respective setting under $CADENAS_USER\psolopt.cfg.

[SETTINGSTABLE]
