This article covers the layout of the file; for the default contents, see iprp_paramtable.2da (contents).

The iprp_paramtable.2da file is the .2da file that defines the various tables used to interpret the "parameter 1" value of an item property.

Each item property has a type corresponding to a row in itempropdef.2da, and the Param1ResRef column of that row is an index into this file (iprp_paramtable.2da). The referenced row from this file then gives the name of a third .2da file to use when interpreting the item property's parameter 1 value, which is an index into that third .2da.

Columns of iprp_paramtable.2da
Name Description
ID (no actual name) Row numbers for the benefit of human readers. The game engine ignores the value in this field, instead generating sequential row numbers as the file is read. It is good practice to keep the entries in this field sequentially numbered to avoid confusion.
Name A StringRef for a name describing what this row represents.
Lable A descriptive name for this row for the benefit of human readers. The game ignores the value of this column (which may be why this column was never changed to "Label").
TableResRef The ResRef of the .2da file (without the .2da extension) to be used to interpret the parameter 1 values of item properties whose type references this row.
