JTable change Column Font

Question

I'm making a table where I want to make the first column with a higher Font Size. For example in column 0 I want Font size of 30 and on columns 1-3 y want Font size of 13. Here's my code ``` import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.io.*; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; import javax.swing.table.*; public class kanji_list extends JFrame { kanji_list(){ JTable table = new JTable(); JScrollPane scroll = new JScrollPane(); Image icon = Toolkit.getDefaultToolkit().getImage("JLPT.jpg"); ImageIcon ima = new ImageIcon("JLPT.jpg"); DefaultTableModel model = new DefaultTableModel(get_data(), get_header()); table = new JTable(model){ public boolean isCellEditable(int rowIndex, int vColIndex){ return false; } }; JTableHeader th = table.getTableHeader(); TableColumnModel tcm = th.getColumnModel(); TableColumn column = null; table.setFont(new Font("Microsoft JhengHei…

In core JTable you basically need a custom renderer which sets the Font to something different from the table's font, f.i. in a subclass of DefaultTableCellRenderer. Note that setting the font on DefaultTableCellRenderer once after instantiation won't work because it's reset on each call to getTableCellRendererComponent.

```
JTable table = new JTable(new AncientSwingTeam());
// the default renderer uses the table's font,
// so set it as appropriate
table.setFont(fontToUseForAllColumnsExceptFirst);
// a custom renderer which uses a special font
DefaultTableCellRenderer r = new DefaultTableCellRenderer() {
    Font font = fontToUseForFirstColumn;

@Override
    public Component getTableCellRendererComponent(JTable table,
            Object value, boolean isSelected, boolean hasFocus,
            int row, int column) {
        super.getTableCellRendererComponent(table, value, isSelected, hasFocus,
                row, column);
        setFont(font);
        return this;
    }

};
// doesn't work because the default renderer's font is reset
// to the table's font always
// r.setFont(font);
// set the custom renderer for first column
table.getColumnModel().getColumn(0).setCellRenderer(r);
```

An alternative is the renderer decoration approach, supported in the SwingX project (biased me can't resist :-) Then the above would be a two-liner (assuming table is of type JXTable):

```
Highlighter hl = new FontHighlighter(font);
table.getColumnExt(0).setHighlighter(hl);
```
