Sort a JTable with fixed / frozen columns

We would assume that the main table and the frozen table use the same table model. In order to have the frozen table sorted as well when the main table is sorted, you can share the table sorter of the main table with the frozen table.

//Make the main table sortable by clicking the column header
mainTable.setAutoCreateRowSorter(true);

frozenTable.setRowSorter(mainTable.getRowSorter());

//After sorting, the same number of row in the table is selected
frozenTable.setUpdateSelectionOnSort(false);

//After sorting, the same number of row in the model is selected
mainTable.setUpdateSelectionOnSort(true);
