Data-table column breaking while hide/show

I am using data-tables for some beautiful features,here i am using data-tables to fix columns of my table

Table structure

• I am making my table with JSON data which is pure dynamic using Java-Script
• Above my table i have a drop-down field which user selects then clicks go and i am showing only that columns which user is selecting
• when user selects 1 or two columns then columns of tbody and thead are breaking
• When i am removing fixedColumn then it is working fine but i need to implement fixedColumn
• The columns i have fixed are also visible twice when i selects dropdowns and press go

Working Code

Note:- I can't use data-table hide/show because i have been using jQuery in my several code and this approach only to hide and show data,I just want o know can We do this with the help of css?
