Actually, I had the allowHtml in my code but not in the example I provided. 
I think my issue is more related to setting properties on a column.

The following statement works (as you pointed out):
data.setProperties(1, 1, {style: 'font-style:italic; font-size:10px;'});

But not this one (which is the one in my current code):
data.setColumnProperties(1, {style: 'font-style:italic; font-size:10px;'});

Any ideas why?

I'm having a hard time finding information on which properties are 
supported for various elements (row, column, cell, etc.). My objective is 
to change the font of an entire column to make it smaller and in italic.

Thanks.
