After spending time with the .if statement, I now understand my "fix"
to your correct syntax changed the meaning.  May I try again?
 
My footnoted table row now looks like this, just as you indicated:

T{
Annualized Return\*[*]
.if !'\n(.z'' .ig
.tm \n(.z
.FS
Compounded Annualized Return 
.FE
T}      abc

but whenever the conditional expression is true, I get errors:

$ make
groff -ms -t -G -p -T dvi -P-l t.ms > t.dvi
<standard input>:9: zero field width
<standard input>:9: warning: can't find character with input code 3
<standard input>:9: zero field width
<standard input>:19: zero field width
<standard input>:19: zero field width
<standard input>:26: zero field width
<standard input>:26: zero field width
:0: macro error: diversion open while ejecting page (recovering)

I get the same errors with 

        .if o .ig
and
        .if !e .ig

and with

        .if !'\n(.z'' foo

"foo" appears in the output.  

The condition is evaluating correctly, but .ig appears to make 
the ms .FS macro unhappy.  

Is there an option in groff similar to the C preprocessor to apply the
macros and output the resulting troff?  If we could see the interaction
of the .ig with .FS, perhaps the "zero field width" message would be
more meaningful.
