Instead of using a basic array to feed data to your table, use a JSON
object. Doing that, you can have all sorts of data in the object, but
only display the information that you ask for in the column headings
array you use to create the table model. Your JSON data might look
like:
[{"rowID":1, "col1":"some data","col2":"more
data"},{"rowID":2,"col1":"my data","col2":"and more data"}]
and your column heading array might then look like:
["col1","col2"] // notice that we aren't using the rowID in the
table, yet the data for it is still there.
When you create your table column model, make sure that you assign the
headings first then assign the data using setDataAsMapArray. If you
don't set the columns first your data won't be able to bind to any
columns and you will get a grid with column heading but no data, don't
ask how I discovered that piece of information.
Tables work very well using JSON, it has allowed us to carry all sorts
of additional information along with the visible data.
Good luck,
Jim
