Editor for 'null' and 'undefined' values

Describe the bug JavaScript distinguish two types of data: null, undefined

And when the editor:“textarea” is handling ‘null’ value it converts value to string ‘null’

I do not expect here ‘null’ string for null value

Tabulator Info

• Which version of Tabulator are you using? 4.1.3
• Post a copy of your construct object if possible so we can see how your table is setup

var tabledata = [
	{id:1, country_id: 1, comment: null  },
	];
  
var table = new Tabulator("#example-table", {
    height:"311px",
    data: tabledata,
    columns:[
        {title:"ID", field:"id", width:40 },
        {title:"Comment", field:"comment", editor:"textarea"},
        {title:"NA", field:"not_exists", editor:"textarea"},
    ],
});

To Reproduce Steps to reproduce the behavior:

1. Go to JS fiddle
2. Click on ‘Comment’ field
3. Click on ‘NA’ field
4. move focus something else compare result at ‘Comment’ and ‘AN’ cells

Expected behavior When editing ‘null’ it should not be converted to ‘null’ string’

Screenshots

possible workaround If there is null just display input’s placeholder. If placeholder is not initialized, just initialize its as ‘null’ when value is ‘null’ or ‘undefined’ when such field does not exists.

Desktop (please complete the following information):

• OS: Linux Mint 18.3
• Browser FF

Hey @olifolkerd

I am not 100% sure, but I think I still have the issue with version 4.2.5.

Here is the updated fiddle from @KES777 with my autocomplete code.

The problem is that Tabulator always writes “undefined” into the cell when I jump in with my tab or mouse.
