Use setValue or setCell on datatable with column id not column index

[John Kilcar]

I'm dynamically creating a datatable based on user choices etc and so can't entirely predict column index positions but can control the column ids.

support documentation seems to indicate that ids can work instead of column indexes.

I have been unable to make this work for  methods suchs as setCall or setValue.

Anyone go some sample script of how this can work, or ideas for a work around.

Thanks in advance
