This tutorial will show you how to asign icon on cell of JTable using CellRenderer, lets begin.
1. Create a JFrame class and add one JTable component from pallet named to
JTableAbstractTableModelWithIcon
2. Declaring variable
private Vector data = new Vector();
3. After initComponent write this code:
table.setModel(new AbstractTableModel() {
String[] colum = new String[]{"No", "Name", "Address"};
@Override
public int getRowCount() {
return data.size();
}
@Override
public int getColumnCount() {
return colum.length;
}
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
return columnIndex == 0 ? "" + (rowIndex + 1) : data.get(rowIndex)[columnIndex];
}
@Override
public String getColumnName(int column) {
return colum[column];
}
});
4. At first column we asign custom cell rendererer: table.getColumn(table.getColumnName(0)).setCellRenderer(new TableCellRenderer() {
private Icon icon = new ImageIcon(getClass().getResource("icon.png"));
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
JLabel label = new JLabel(value.toString());
label.setIcon(icon);
label.setOpaque(true);
label.setBackground(table.getBackground());
label.setForeground(table.getForeground());
if (isSelected) {
label.setBackground(table.getSelectionBackground());
label.setForeground(table.getSelectionForeground());
}
if (hasFocus) {
label.setBorder(BorderFactory.createLineBorder(Color.RED));
}
return label;
}
});5. Finally add some data: data.add(new String[]{"", "Sri Kuntadi", "Purwodadi"});
data.add(new String[]{"", "Fajar Ichwanul Arifin", "Cilacap"});
data.add(new String[]{"", "Arif Nurcahyo", "Magetan"});
data.add(new String[]{"", "Muh Adly Hamid", "Makasar"});
6. Now run project and you will get like this:
