Answer 1

I need to create a rowheader for the jtable.

Check out the Fixed Column Table.

You create a normal TableModel. Then you can specify the first row of the model to be used as the row header. The code will then create two table that share the same TableModel. One table will be used as the row header, the other will be displayed in the viewport of the scroll pane.

If you want to sort the tables you will then also need to share the RowSorter with code something like:

table.setAutoCreateRowSorter(true);
fct.setRowSorter(table.getRowSorter());
table.setUpdateSelectionOnSort(true);
fct.setUpdateSelectionOnSort(false);
