Change string col box width in a table box

[#1]

I'm trying to display long text in a string col box in a table box window and have them wrap visually across multiple lines without modifying the underlying text data. I've found some ideas in this post and this post but I can't make them work for a string col box.

Here's a minimal example to illustrate my issue, here I would like to make the string col box behave like the col box :

longstring = "toooooooooooooooooooooo looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong teeeeeeeeeeeeeeeeext.";
nw = New Window( "Display",
	tb = Table Box(
		col1 = Col Box( "Mycolbox" ),
		col2 = String Col Box( "Mystringcolbox", longstring )
	)
);

col1 << append( Text Box( longstring , <<set wrap( 350 ) ) );

I'm looking for a solution that change the display and not the string themselves, and applies as a post-proccessing step after the window is made.

Thanks in advance

I don't think you can wrap the text in string col box and that is why you have to rely on col box + text box.
