javascript - Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined Datatables

I am getting this error:

Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined

I searched the web and found that it usually occurs when the count of th mismatches the count of td.

But I don't think that is causing the problem. See the table defination below :

$(document).ready(function() {
    $('#chat').DataTable({
        responsive: true,
        "bLengthChange": false,
    });
});

DataTables expects the table to be populated consistently with each row, with the same number of columns. The cause is the empty elements in your HTML.

<tr>
</tr>

If you remove those empty rows, the error will go.

Just an FYI: datatables also do not play well with colspan. I have a table with 3 cells, but one colspan=3 row and they give the same error.
