how to change the width of columns in Change tab of Part?

Hello. Is there any solution for this? I have changed column width of the property but still its not reflecting in relationship tab. Please let me know if there is any solution. Thanks in Advance.

I assume you have figured this out but if not from the base Item Type which is Part go to the Relationships Types and double click the relationship you are interested in.  From that Relationship item you have a Relationship View tab.   If it is a grid you will see it listed in the Grid column and go click the link to get to it.   If you see a Start Page that has TGV in it the tab is a Tree Grid View (Grids and TGV do visually look different also).   In the case of the Changes on Part R22 shows it as a TGV an so has the guid which you can query RB_TREEGRIDVIEWDEFINITION in SQL to find the name which is PE_Changes for yours.   Once in the TGV it will take you 2 minutes to adjust the widths.
