please let me know how to configure my code.

public void displayTable(JTable table){

    Vector columns = new Vector(getIndividual(0).chromosomeColumnCount()+1);

    columns.add("Staff Names");

        for(int i=0; i<getIndividual(0).chromosomeColumnCount(); i++){
             columns.add(RosterManager.getDay(i));
        }

        Vector data = new Vector();
        Vector row;

        for(int row1=0; row1<getIndividual(0).ChromosomeRowSize(); row1++){

            row = new Vector(getIndividual(0).chromosomeColumnCount());
            row.add(RosterManager.getNurse(row1).getEmpName());
            for(int col=0; col<getIndividual(0).chromosomeColumnCount(); col++){
                row.add(getIndividual(0).getShift(row1, col).getShiftName());
            }    
            data.add(row);
        }
        DefaultTableModel tableModel = new DefaultTableModel(data, columns);

        table.setModel(tableModel);
}

Answer 1

setPreferredWidth(27) can be used. Inside the method you have to add a dimension.

Answer 2

Something like this:

//table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    TableColumn column = null;
    for (int i = 0; i < cols.length; i++) {
        column = table.getColumnModel().getColumn(i);
        if(i == 0 ) column.setPreferredWidth(10);
    }

Answer 3

Im using this method to change the width of columns of JTables. Just add this to your displayTable() method.

your_table_name.getColumnModel().getColumn(0).setPreferredWidth(50);
your_table_name.getColumnModel().getColumn(1).setPreferredWidth(100);

Answer 4

JTableName.getColumn(Object identifier).setWidth(WIDTH);

JTableName.getColumn(Object identifier) will return the column and set Width will change its width.
