editing tables.sds

Hi everyone. I need you help.


 




Right now I'm trying to create a little mod for M2. And I have a problem. I open tables.sds using Rick's tools, and, as you know, there are .xml files and table file. That table file consist of many settings, this settings can change the gameplay and make it harder. But when I try to save my changes, 'save' button is grey, so I can't change this parametres.


 




I've seen a lot of mods with changed weapons parametres. So, please, can you tell me, how can I change this table ?


 




Sorry for my bad English
