When I add a row, it popup warning

knvb

I am preparing an user management with datatable plugin.
It works fine.
However,I add the attribute data-order="0,1000" to the first column of the first row for keeping the "anonymous" row always on top.
When I click on the upper left hand corner "+" , I got a warning message in the .png file of attachment.
How can I fix the problem?
I attached a zip file for your reference.
All related files are stored in the zip file.

The problem is that you are adding data to the table in a different format from that which DataTables has automatic read the data in from the HTML as. Using the data-order attribute means that you need to provide two data points for that column. This is the structure to use:

  userTable.row
    .add([
      {
        "@data-order": "10000",
        "display": '<input type="text">'
      },
      "<input type=text>",
      "&#x271A;",
      "<input type=checkbox>",
      "&#x2796;"
    ])
