Adding a sort to an existing table

Hi, I have data table that I have generated, formatted, made sure is sensible in all different screen widths etc.
Now I wish to add sort to the headers. According to a youtube tutorial I should be able to do this by clicking ‘Run’.

The Server Connection is shown with the opportunity to add a state mgr etc.

However, the Server Connection is blank for me, if I persist then my existing table gets overwritten by a new table.

How can I add a sort to an existing table please?

If you do not want to create a new table (don’t see why), then you could always create a new page with a new table. Then transfer the extra code to the original table.

Thanks Ben, not a bad workaround. Its just that the ‘Run’ should bring up the existing server connect, but it does not. Maybe should be looked at. In the mean time I will use your suggestion
