  Going to need a little more to go on than an empty post! Could you fill in the template text please, with a link to your test case so we can offer some help and also describe the issue.

  I init a FixedColumns table，use options of “ajax” to call data，and options of "columns" to build column's title and render based on a time range selector.
  Just entered the page,table is ok :

  <table id="dt-table"></table>
$(function() { initTable()});
  

  

  then, I change time range selector , for example,change time range from 3.1-3.7 to 4.2-4.20.now click a button ,I want to change value of options "columns", Rerequest the protocol and draw the table with 4.2-4.20:

  $('#searchBt').on('click', function () { initTable(); })
  But it can't live up to that expectation.thead is disappeared,and console report an error:
  
  

  It's even stranger that I click the button second time,table is right.the third time is Wrong.For the fourth time is right.So on and on

  how do I change the "columns" options correctly in FixedColumns dataTable~~~~

  Most Datatables options, including columns, don't have a way to change the config dynamically. The destroy() API or destroy option is used to change the config options. This requires reinitializing the Datatable.
