I do not know how to give a live example as the Editor is not available via CDN to link to the live editor. However, I am having a problem controlling the inline field width when a cell is edited.
The best way to describe it is, if the table's column header is 2 letters:
<table>
<thead>
<tr>
<th>CT</th>
<tr>
</thead>
</table>
When you click in the cell to edit it, nothing is shown. I can add a few more letters to the name, and it will then start to show data. I have tried a bunch of semantic css as well as:
{
targets:[0],
width: "50%"
},
But nothing seems to fix it until I remove the "form" class from the cell, which at that point it turns it into datatables input field.
