How do you remove selected rows from a JTable?

Question

I\'ve tried this:

public void removeSelectedFromTable(JTable from)
{
    int[] rows = from.getSelectedRows();
    TableModel tm= from.getModel();

    while(         


        

Answer 1

This worked for me

int numRows = table.getSelectedRows().length;
for(int i=0; i<numRows ; i++ ) {

    m_tableModel.removeRow(table.getSelectedRow());
}

Answer 2

Why not just use this,

public void removeSelectedFromTable(JTable from)
{
        int[] rows = from.getSelectedRows();
        TableModel tm = (DefaultTableModel) from.getModel();


        for (int row : rows) {
            tm.removeRow(from.convertRowIndexToModel(row));
        }

        from.clearSelection();
}

Answer 3

That solution works with header sorting and updates automatically the table (i.e.: it is not required to rebuid it).

The "Collecions.sort in reverse order" ennables to avoid IndexOutOfBondException.

private void deleteSelectedRows() {
        int[] selectedRows = table.getSelectedRows();
        table.clearSelection();

        // get model rows
        List<Integer> selectedModelRows = new LinkedList<Integer>();
        for (int i =`enter code here` 0; i < selectedRows.length; i++) {
            selectedModelRows.add(table.convertRowIndexToModel(selectedRows[i]));
        }

        Collections.sort(selectedModelRows, Collections.reverseOrder());

        for (int selectedModelRow : selectedModelRows) {
            tableModel.removeRow(selectedModelRow);
            tableModel.fireTableRowsDeleted(selectedModelRow, selectedModelRow);
        }
}

Answer 4

Java 8+ streaming solution:

JTable table;
DefaultTableModel model = (DefaultTableModel) table.getModel();

IntStream.of(table.getSelectedRows())
            .boxed()
            .sorted(Collections.reverseOrder())
            .map(table::convertRowIndexToModel) // support for sorted table
            .forEach(model::removeRow);

Answer 5

removeRows: {
    int[] lines = t.getSelectedRows();
    if(lines.length==0)
        break removeRows;
    for(int i=0; i<lines.length; i++) {
        lines[i]=t.convertRowIndexToModel(lines[i]);
    }
    Arrays.sort(lines);
    for(int i=lines.length-1; i>=0; i--) {
        dtm.removeRow(lines[i]);    
    }
}

Working with sorting, moving columns, multiple selection, etc.

Answer 6

It doesn't work, this is better:

public void removeSelectedRows(JTable table){
   DefaultTableModel model = (DefaultTableModel) this.table.getModel();
   int[] rows = table.getSelectedRows();
   for(int i=0;i<rows.length;i++){
     model.removeRow(rows[i]-i);
   }
}
