JTable Column Headers with wrapped and center aligned text

Question

I am currently trying to wrap and align center text of a column header. The problem seems to be that while the first line of column header is aligned, the second one does not get aligned properly.

I am using DefaultTableCellRenderer to render it as such:

public void centerAlign(JTable t, int numberOfColumns){
    centerRenderer.setHorizontalAlignment(SwingConstants.CENTER);
    for (int i = 0; i < numberOfColumns; i++){
         t.getColumnModel().getColumn(i).setCellRenderer(centerRenderer);
    }
    headerRender = (DefaulttableCellRenderer)
    t.getTableHeader().getDefaultRenderer();
    headerRenderer.setHorizontalAlignment(JLabel.CENTER);
}

you define 'headerRender' but then call it 'headerRenderer' when you set the alignment on the last line. — Reddy, Oct 20 '16 at 12:28

In your table model class use html of column name

example:

"<html><center>First column</html>"
