I see that you're on excel, so you exported the bill of materials to excel, or do you use an Excel-based bill of materials? In this case I assume that the sheet is protected,
I just discovered that to move a column by hand it's a little different from excel where you move the column width to the top of the column while in Soliworks you have to select the vertical lines in the middle of the page (the top of the column being inactive).
On the other hand, there is no dynamic interaction between the BOM and the excel file, which means that if you modify the ASM, the changes are not reflected in the excel file.
If you know how to do it, please sir, tell me everything!
Apparently the trick of linking a BOM is from an assembly BOM and on a referenced drawing not on an external file, it may be feasible via a macro or other,
