textarea with formatting & styling

[devnull]

I need to create a multiline text area, that will allow the user to paste rows from an excel spreadsheet and maintain the column widths, rows etc.

But I also need to allow normal text in the text box and this needs to be done without the user having any knowledge of HTML tables etc etc. - this is absolutely critical.

A WYSIWYG editor will be an overkill for this, I know this feature is not supported, but any suggestions on how I could go about achieving this, something like codeEditor.
