Question

I want to do a JTable with column names, using:

JTable(Vector rowData, Vector columnNames)

to constructs a JTable to display the values in the Vector of Vectors, rowData, with column names, columnNames.

So, I did this:

final String[] columnNames = {"NOMBRE", "DÍAS DE LA SEMANA", "HORA DE INICIO", "HORA DE FIN", "TIEMPO MÁXIMO DE USO"};

        rs.last();
        int numRows = rs.getRow();
        rs.beforeFirst(); 

        Object[][] columnData = new String[numRows][5];

        int i = 0;
        while(rs.next()){

            columnData[i][0] = rs.getString(1);
            columnData[i][1] = rs.getString(2);
            columnData[i][2] = rs.getString(3);
            columnData[i][3] = rs.getString(4);
            columnData[i][4] = rs.getString(5);

        }

table = new JTable(columnData, columnNames);
        table.setBounds(300,600,700,150);

But I only see the data, why isn’t the title shown?

Thank in advance

Answer 1

JTable table = new JTable(columnData, columnNames);
JScrollPane scroll = new JScrollPane(table);
panel.add(scroll);
