Refresh a single table row?

Hi,

how can I refresh a single table row?

I have two tables that depend on each other. Imagine Table1 has a column that displays the sum of all entries in Table2. If I add an entry to Table2, I of course want the currently selected row in Table1 to update the sum.

table.refreshRowCache();

This is how I’m doing it at the moment, but this refreshes the whole “parent” table, which is not necessary. It would be sufficient to just refresh the cache of a single row. How can this be achieved?

Thanks
