public static int getMaxColumnWidth(JTable table, int column) {

  Font font = table.getFont();
  FontMetrics metrics = table.getGraphics().getFontMetrics(font);
  String header = table.getColumnName(column) + "   "; // Whitespace buffer as a crude way (hack)
                              // to account for the rendering context
  Test.output("Column name: " + header);
  // Convert from string length in characters to pixels
  int widest = metrics.stringWidth(header) + (2 * table.getColumnModel().getColumnMargin());
  Test.output("Starting widest value: " + header + " (" + widest + " pixels)");
  // Now go through each row to see if there is a longer value in the column
  int rows = table.getRowCount();
  Test.output("Row count: " + rows);
  for (int index = 0; index < rows; index++) {
    String cellValue = table.getValueAt(index, column).toString();
    int cellWidth = metrics.stringWidth(cellValue) + (2 * table.getColumnModel().getColumnMargin());
