How to fix the size of row on BOM table?

Hi

I have a problem on BOM table, I made same size row on BOM, but when you edit BOM, the size of row you edited, automatic changed, you have to resize all table, do we have any way make all row on BOM fixed? so when you edit BOM, the size of row will not change.

Thanks
