Datatables: Cannot read property 'mData' of undefined

Thriveni picture Thriveni · Aug 19, 2014 · Viewed 339.1k times · Source

I have an issue with Datatables. I also went through this link which didn't yield any results. I have included all the prerequisites where I'm parsing data directly into the DOM. Kindly help me to fix this issue.

Script

$(document).ready(function() {
  $('.viewCentricPage .teamCentric').dataTable({
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "bPaginate": false,
    "bFilter": true,
    "bSort": true,
    "aaSorting": [
      [1, "asc"]
    ],
    "aoColumnDefs": [{
      "bSortable": false,
      "aTargets": [0]
    }, {
      "bSortable": true,
      "aTargets": [1]
    }, {
      "bSortable": false,
      "aTargets": [2]
    }],
  });
});

FYI dataTables requires a well formed table. It must contain <thead> and <tbody> tags, otherwise it throws this error. Also check to make sure all your rows including header row have the same number of columns.

The following will throw error (no <thead> and <tbody> tags)

<table id="sample-table">
    <tr>
        <th>title-1</th>
        <th>title-2</th>
    </tr>
    <tr>
        <td>data-1</td>
        <td>data-2</td>
    </tr>
</table>

The following will also throw an error (unequal number of columns)

<table id="sample-table">
    <thead>
        <tr>
            <th>title-1</th>
            <th>title-2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>data-1</td>
            <td>data-2</td>
            <td>data-3</td>
        </tr>
    </tbody>
</table>
