How can I change the column width in a child table?

Is there any option other than ‘toggle full width’, to show the whole content of ITEM-Code?

I already shortend the part-numbers, but I can not ready most of the ITEM-Names.
When I create a purchase recipet, it is sooo hard, to check the content, when you cant read the ITEM-Code…

Did you already try to change the width of the column via the gear icon in the top right of the table?

Looks like it is set to 2 in your case. You could decrease the with of “Required By” and “Rate” to 1 and increase “Item Code” to 4.
