Get row by index from JTable

问题

How to get row with index i froj JTable ? I looked at member functions but there is nothing like getRowAt . Can anybody help ?

回答1:

There is no "row" object for a table, so nothing you could get with a getRow method.

You can ask getValueAt() to get the individual values, use it for each column and you have your complete row.

回答2:

AFAIK, there is no such method. Write something like that:

public String[] getRowAt(int row) {
     String[] result = new String[colNumber];

     for (int i = 0; i < colNumber; i++) {
         result[i] = table.getModel().getValueAt(row, col);
     }

     return result;
}

P.S - Use table.getValueAt() if you want to respect a rearranged by the user column order.

回答3:

I recommend to create a TableModel based on a list of POJOs.

It's then easy to add a method like:

   MyPojo getData(int index);

Have a look at this sample I wrote some time ago for a starting point: http://puces-samples.svn.sourceforge.net/viewvc/puces-samples/tags/sessionstate-1.0/sessionstate-suite/sessionstate-sample/src/blogspot/puce/sessionstate/sample/ParticipantTableModel.java?revision=13&view=markup

Try something like this

private void getIndexRow(){
    int i;
    int row = 0;
    int column = 0;
    i=Integer.parseInt(myTable.getValueAt(row,column).toString());
}

Another way of doing it is using the table model's getDataVector() method.

DefaultTableModel tm = (DefaultTableModel) table.getModel();
Vector<Object> rowData = tm.getDataVector().elementAt(rowIndex);

回答6:

 private void jTable1MousePressed(java.awt.event.MouseEvent evt) {                                     

    int selectedRow;

    ListSelectionModel rowSM = jTable1.getSelectionModel();

      rowSM.addListSelectionListener(new ListSelectionListener()
      {
        @Override
        public void valueChanged(ListSelectionEvent e) 
        {
            ListSelectionModel lsm = (ListSelectionModel) e.getSource();

            selectedRow = lsm.getMinSelectionIndex();

            int numCols = jTable1.getColumnCount();

            model = (DefaultTableModel) jTable1.getModel();

            System.out.print(" \n row " + selectedRow + ":");

            for (int j = 0; j < numCols; j++) 
            {
                System.out.print(" " + model.getValueAt(selectedRow, j));
            }

        }
    });
}

Using this you can get value of whole row where u click on particular row.

回答7:

This function is working well for me.

private Object[] getRowAt(int row, DefaultTableModel model) {
    Object[] result = new Object[model.getColumnCount()];

     for (int i = 0; i < model.getColumnCount(); i++) {
         result[i] = model.getValueAt(row, i);
     }

     return result;
}
