54 * When making use of DataTables' x-axis scrolling feature, you may wish to

56 * exactly this option (note for non-scrolling tables, please use the
57 * FixedHeader plug-in, which can fix headers and footers). Key
58 * features include:
59 *
60 * * Freezes the left or right most columns to the side of the table
61 * * Option to freeze two or more columns
62 * * Full integration with DataTables' scrolling options
63 * * Speed - FixedColumns is fast in its operation
