Script to loop thru and group columns by name, dynamically

So I'm trying to figure this out and its just not quite working.

 

I've got a table with a key-value pair that I've SPLIT from Tall to Wide. I end up with about 10k columns that all have a regular naming structure, like 
"15.02.0 param1", "15.02 param2", "15.02 param3"...."15.03 param1", "15.03 param2", "15.03 param3",...

 

How can I look through all these columns and group them dynamically by the starting term? ie. all 15.02% columns in a group, all 15.03% cols, all 15.04%, ... all 17.06%....and name the group based on the groupby number?

 

My script just groups everything into a single group. ug.

 

//**split Aggregate Data from TALL to WIDE, grouping WIDE columns by StepID
dt = current data table();
Summarize( dt, RecipeStepIndex = by( :RecipeStepId) );//get list of unique RecipeStepID's

//split the table TALL to WIDE
dt << Split(
       Split By( :RecipeStepId, :ParameterName, :AggregateFunction ),
       Split( :Value ),
       Group( :Recipe, :ProcessTime, :Tool, :Chamber, :Lot, :WaferScribe ),
       Output Table( "AggWide" ),
       Remaining Columns( Drop All ),
       Sort by Column Property,
       dt << sort( by( :Recipe, :Tool, :Chamber, :Lot, :WaferScribe ))
); dtAggWide = current data table(); ColNamesList = dtAggWide << get column names(string, continuous); //get the column names of the WIDE table //Create an empty list for the matching columns RecipeStepList = {}; // Find matching column names For( i = 1, i <= N items( RecipeStepIndex ), i++, For( j = 1, j <= N Items( ColNamesList ), j++, If( Contains( ColNamesList[j], RecipeStepIndex[i] ), Insert Into( RecipeStepList, ColNamesList[j] ), ); ); ); // If groups of columns are found, create Col groupings If( N Items( RecipeStepList ) > 0, dtAggWide << select columns( RecipeStepList ); dtAggWide << group columns(); );

Any way to make this search for a specific character, then use that as the group name? That way its a dynamic length for the first section?

You would modify the part where col_group is determined and then continue accordingly.
