In a drawing the Parts List behaves differently to a General Table and all other tables we are used to (e.g. Excel).
Resize a column by dragging the column divider. In a General Table and Excel the column to the left of the manipulated divider resizes. For a Parts List it is the column to the right of the manipulated divider that gets resized.
Please make the Parts List column resize work the same as General Tables and other Windows based tables.
