JTable Class
First, let's look at the JTable class, which gives you a way to display data in tabular form
(see Figures 18-1 and 18-2).
Creating a JTable
You have seven different ways to create a JTable . The various constructors allow you to create
tables from a number of data sources.
public JTable()
JTable table = new JTable();
public JTable(int rows, int columns)
JTable table = new JTable(2, 3);
public JTable(Object rowData[][], Object columnNames[])
Object rowData[][] = { { "Row1-Column1", "Row1-Column2", "Row1-Column3"},
{ "Row2-Column1", "Row2-Column2", "Row2-Column3"} };
Object columnNames[] = { "Column One", "Column Two", "Column Three"};
JTable table = new JTable(rowData, columnNames);
public JTable(Vector rowData, Vector columnNames)
Vector rowOne = new Vector();
rowOne.addElement("Row1-Column1");
rowOne.addElement("Row1-Column2");
rowOne.addElement("Row1-Column3");
Vector rowTwo = new Vector();
rowTwo.addElement("Row2-Column1");
rowTwo.addElement("Row2-Column2");
rowTwo.addElement("Row2-Column3");
Vector rowData = new Vector();
rowData.addElement(rowOne);
rowData.addElement(rowTwo);
Vector columnNames = new Vector();
columnNames.addElement("Column One");
columnNames.addElement("Column Two");
columnNames.addElement("Column Three");
JTable table = new JTable(rowData, columnNames);
public JTable(TableModel model)
TableModel model = new DefaultTableModel(rowData, columnNames);
JTable table = new JTable(model);
public JTable(TableModel model, TableColumnModel columnModel)
// Swaps column order
TableColumnModel columnModel = new DefaultTableColumnModel();
TableColumn firstColumn = new TableColumn(1);
firstColumn.setHeaderValue(headers[1]);
