Powerpoint - how to format text?

Hi,

After finding seemingly no information on searching for this on the forum, It thought it best to ask here:

Is it possible to format text in Powerpoint slides?

Here's an example of what I want to do - I have a variable name, like "Strychnine IC50" which I put into a table, which is then

displayed in a powerpoint slide.  However, I want it output in the powerpoint slide like this - "Strychnine IC 50

(the number '50' is supposed to be in subscript).

So, how would I say, apply this subscript formatting to my table header name?  I can't enable HTML tags in a Table for

some reason, if powerpoint can even interpret HTML tags, let alone when in a variable name.

Thanks in advance,

Ed.
