dynamic rowheight for JTable

[Venkata Cherukuri]

How can I have my JTable display varying Row Height. This one should work the same way as Excel- where in You can drag a row and it's height increases.

I use this code when a value changes to calc row height. You will need to determine when to call this. It works for the most part. I haven't devoted the time to make it perfect. Might save you some time.

            note = dataModel.getValueAt(row, dataModel.TEXT).toString();
            // Reliable way to calculate how long a field is
            Graphics2D g = (Graphics2D) notesPanel.getGraphics();
            FontRenderContext frc = g.getFontRenderContext();
            Font font = g.getFont();
            Rectangle2D bounds = font.getStringBounds(note, frc);
            dataWidth = bounds.getWidth();
            BigDecimal biDataWidth = new BigDecimal(dataWidth);
            BigDecimal rowDivisor =
                new BigDecimal("" + dataModel.getColumnWidth(dataModel.TEXT));
            int rowHeight =
                (biDataWidth.divide(rowDivisor, BigDecimal.ROUND_DOWN)
                            .add(new BigDecimal("1"))
                            .multiply(new BigDecimal("" + TABLEHEIGHT))).intValue();
            notesTable.setRowHeight(row, rowHeight);
