this code export columns, 

exportoptions: {     columns: [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,... ] }

i ve more 20 columns , user can select 5 columns in front end( via colvis plugin).

if user select 5 columns columns should exported.how can this?

if using colvis can columns visible

exportoptions: {    columns: ':visible' }

this jquery table , use columns visible in browser.

if want use same model colvis uses have bit more fansy/hacky. how did in relation using responsive plugin:

exportoptions: {    columns: exportcolumns }  function exportcolumns(i, values, header){    var colvis = $(header).closest(".datatable").datatable().columns().visible();       if(colvis[i]){          return values;       }     }
