When displaying large amounts of data in a table, it can often be useful for the end user to have the column titles (the thead element as a whole in fact) always visible. This is particularly true if using DataTables with pagination disabled, or the display length is set to a high value.
The FixedHeader extension for DataTables will ensure that your column titles will scroll with the page, showing at the top of the table at all times. Try the demo shown below - you might want to try resizing the window for full effect! Note also that the column titles remain clickable to perform sorting on the table.
FixedHeader is initialised using the constructor new $.fn.dataTable.FixedHeader(); - shown below.
