Multiple Column Sortings in JTable

Question

I know that I JTablecan sort by one column. But is it possible to allow sorting multiple columns or do I need to write the code myself?

Answer 1

You can sort by multiple columns by specifying more than one sort key when calling setSortKeysin RowSorterwhich you are using.

Answer 2

You should be able to install the associated TableRowSorter and Comparator. Example:

TableModel myModel = createMyTableModel();
JTable table = new JTable(myModel);
TableRowSorter t = new TableRowSorter(myModel);
t.setComparator(column that the comparator works against, Comparator<?> comparator);
table.setRowSorter(new TableRowSorter(myModel));

Answer 5

Sorting and filtering the table is controlled by the sorter object. The easiest way to provide a sorter object is to set the autoCreateRowSorter property to true:

JTable table = new JTable();
table.setAutoCreateRowSorter(true);

This action defines the row sorter, which is an instance of javax.swing.table.TableRowSorter.
