It gets very hard to tell which datasource a column is pulling from.
Example of problem:
I have a few thoughts on ways to reduce confusion:
I think #2 is best for "non-programmers" but #1 or #3 probably provides more flexablity.
It would also be nice to have a function like GetColumnNames(table/datasource)
It would also be nice if ClearCollect had a simple way to build an empty collection with just the column names so I don't have to do: ClearCollect(col_Temp,Datasource);Clear(col_Temp)
