HI Marco,
Are you not in control of the data at the server side? The easiest thing to
do is to arrange to send the data from the server as an array of arrays,
instead of as an array of objects.
You do have an alternate means to accomplish this, however. In addition to
the setData() method in the table model, there is also a setDataAsMapArray()
which takes something either very like, or exactly what your server is
currently sending. In order to use this method, you must assign IDs to each
column so that it knows how to parse the map into the appropriate columns.
You assign IDs using the second parameter of setColumns(). The first
parameter, which you're already using, is the array of column names. The
second parameter is an array of column IDs which are the keys in the map
(col1, col2, etc. in your example).
One of those options should get you off and running.
