Sortable: placeholder for sortable tbody elements is not visible

[oemmes]

When using a sortable for tbody elements of a table the created placeholder (when dragging an tbody element) is not visible.

The reason is that the placeholder is an empty tbody. The tbody needs a tr and td which gives it a height to be visible. This is already implemented for tr placeholders which also need a td element in it.

I created a pull request on github to fix this: ​https://github.com/jquery/jquery-ui/pull/1380

Sortable: Append a tr with td to the placeholder of tbody elements

When sorting tbody elements of a table the placeholder needs to have a tr with td elements to be visible. The appended elements are created in the same way as for the placeholder of a tr element; the first row of the sorted tbody is used for that.

Fixes #10682 Closes gh-1380
