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~~~~

Does it have a way to change option item to update? like setOption()、update()

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.
