sometimes when we use Datatables, Datatables table header or column does not aligned or matched with the table body width .here are two solutions, check which one work for you-
Solution 1: table width 100%
Give your table a style of width 100% for example width=”100%”
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<table class="table table-striped" id="emptableid" width="100%"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> </tbody> </table> |
Solution 2: use DataTables fixcolumn cdn /columns.adjust()
add or use fixColumn CDN( https://cdn.datatables.net/fixedcolumns/ ) CSS and js file in your code for that
|

<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/fixedcolumns/3.3.0/css/fixedColumns.dataTables.css"> <script type="text/javascript" src="https://cdn.datatables.net/fixedcolumns/3.3.0/js/dataTables.fixedColumns.js"></script> |
and add columns.adjust()
var table = $('#example').DataTable();table.columns.adjust().draw();for example
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 |

You can also write this way that part
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<script type="text/javascript"> $(document).ready(function() { var temployee= $("#emptableid").DataTable({ "initComplete": function( settings, json ) { temployee.columns.adjust().draw(); } }); }); </script> |
