Method

voidadjustColumnSizes(JTable table, int column, int margin)
Method sets columns width to the widest value 
DefaultTableColumnModel colModel = (DefaultTableColumnModel) table.getColumnModel();
TableColumn col = colModel.getColumn(column);
int width;
TableCellRenderer renderer = col.getHeaderRenderer();
if (renderer == null)
    renderer = table.getTableHeader().getDefaultRenderer();
Component comp = renderer.getTableCellRendererComponent(table, col.getHeaderValue(), false, false, 0, 0);
width = comp.getPreferredSize().width;
...
voidautoSizeCols(JTable table)
auto Size Cols 
if (table == null || table.getColumnCount() == 0) {
    return;
TableColumnModel columnModel = table.getColumnModel();
for (int col = 0; col < table.getColumnCount(); col++) {
    int maxwidth = 0;
    for (int row = 0; row < table.getRowCount(); row++) {
