Need some help understanding modifying 2da's

[Daeros_Trollkiller]

I am having some trouble wrapping my head around modifying existing 2DA's.  The specific one I am trying to modify in this case is: rndmagic.2da.  I am trying to add some additional ammunition types to the "HIGH" row:

2DA V1.0
*
       2        3        4        5      6        7        8      9       10       11       12       13       14       15       16       17       18        19        20
LOW    RNDWEP02 RNDWEP01 BULL03*3 POTN31 RNDSCR02 RNDSCR01 SCRL06 SCRL04  POTN08   POTN43   POTN44   POTN37   POTN19   POTN28   BULL02*5 AROW02*5 BOLT02*5  RNDWEP01  RNDWEP02
HIGH   RNDWEP03 RNDWEP02 RNDWEP01 SCRL08 SCRL09   RNDSCR03 SCRL16 POTN17  POTN08   POTN10   AROW04   AROW09   BOLT04   BOLT03   AROW06   RNDWEP01 RNDWEP02  RNDWEP02 RNDWEP03

I am trying to add 5 new items, essentially trying to make something like this:

 

LOW    RNDWEP02 RNDWEP01 BULL03*3 POTN31 RNDSCR02 RNDSCR01 SCRL06 SCRL04  POTN08   POTN43   POTN44   POTN37   POTN19   POTN28   BULL02*5 AROW02*5 BOLT02*5  RNDWEP01  RNDWEP02	*		  *			*		  *			*			
HIGH   RNDWEP03 RNDWEP02 RNDWEP01 SCRL08 SCRL09   RNDSCR03 SCRL16 POTN17  POTN08   POTN10   AROW04   AROW09   BOLT04   BOLT03   AROW06   RNDWEP01 RNDWEP02  RNDWEP02  RNDWEP03	BULL07    BULL08	BULL09	  BDBOLT01	BDBOLT02

 

Here is the code I've tried, and I'm sure I am missing something, hoping it's something simple:

//COPY_EXISTING ~rndmagic.2da~ ~override~
//BEGIN
    //SET_2DA_ENTRY 3 21 3 ~bull07~
        //SET_2DA_ENTRY 3 22 3 ~bull08~
            //SET_2DA_ENTRY 3 23 3 ~bull09~
                //SET_2DA_ENTRY 3 24 3 ~bdbolt01~
                    //SET_2DA_ENTRY 3 25 3 ~bdbolt02~
                        //END

Anything that will help me to better understand how these files, and modifying them in WeiDu works is greatly appreciated!

Well, they work by a dice roll of a 20 sided die. And so there's already a 20 results.

Not something this simple, you wanted, is my bet.

You can't add columns that way. SET_2DA_ENTRY edits existing entries, it doesn't add new ones. You would need to use an APPEND_COL to add new column data.

Unfortunately, in this case I don't think it will help you. I'm fairly sure (as Jarno alludes to) that the range in rndmagic and the other BG2-style random-treasure files is hardcoded and won't be changed by editing the files. (I admit I haven't tested it, but that's what IESDP says.)

Assuming you're modding an EE game, you could try using the IWDEE random-treasure system, which is a bit more flexible.
