[Solved] Set the row height and column width of JTable

import javax.swing.JTable;

public class TableTest {
      public static void main(String[] args) {
            JTable myTable = new JTable();

           //Set the height of  all rows
            myTable.setRowHeight(50);
           //myTable.setRowHeight(myTable.getRowHeight() + 10);

          //Set the height of one particular row.
          //Works only after calling the setModel method of JTable
          //Need to reset each time table data is modified
          //set the height of row 3 to 50
         MyTableModel model = new MyTableModel();
          myTable.setModel(model);
         myTable.setRowHeight(3, 50);
        //myTable.setRowHeight(3, myTable.getRowHeight(3) + 10);

        model.addTableModelListener(new TableModelListener() { 

             @Override 

            public void   tableChanged(final TableModelEvent e) { 

                  EventQueue.invokeLater(new Runnable() {  

                       @Override 

                       public void run() { 

                              myTable.setRowHeight(3, 50); 

                      } 

                }); 

             } 

         });

         //Set column width         
        TableColumnModel columnModel = myTable.getColumnModel();
         columnModel.getColumn(0).setPreferredWidth(200);
         columnModel.getColumn(1).setPreferredWidth(120);
         columnModel.getColumn(2).setPreferredWidth(150);
        columnModel.getColumn(3).setPreferredWidth(180);
    }

}
