jQuery DataTables console error - Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined

[alulsh]

When you initially load https://www.alexandraulsh.com/family-tree-map/ you see the following error in the browser console:

Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined
    at rt (jquery.dataTables.js:3140)
    at X (jquery.dataTables.js:2453)
    at HTMLTableRowElement.<anonymous> (jquery.dataTables.js:2481)
    at jquery.js:208
    at Function.map (jquery.js:463)
    at w.fn.init.map (jquery.js:207)
    at J (jquery.dataTables.js:2479)
    at N (jquery.dataTables.js:1281)
    at HTMLTableElement.<anonymous> (jquery.dataTables.js:1306)
    at Function.each (jquery.js:381)

The error has no effect on application functionality and you can load a GEDCOM file successfully.

Per https://stackoverflow.com/a/35928281, this error is likely happening because we initialize a blank empty table with only a thead with six table headers (th) and no td elements.

Adding a tbody with a table row and 6 tds does resolve the error:

<tbody>
  <tr>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
  </tr>
</tbody>

Unfortunately, with the new table row, the DataTables search helper initializes twice, despite only intending to initialize DataTables once:

If you load a GEDCOM file, one table stays with 1 result. The other table processes the GEDCOM file, so it is likely that DataTables may be initialized twice.
