I tried to write a macro for a TABLE line:
\def\TestCmd{\dodoubleempty\doTestCmd}
\def\doTestCmd[#1][#2]#3{\bTR\bTD #3
    \iffirstargument\hfill (#1)\fi
    \eTD \bTD
    \ifsecondargument
        3: #2 and #3
    \else
        2: only #3
    \fi
    \eTD\eTR
}
But it never goes into "else" (if #2 is empty, I get "3: and #3")!
And it's only with the table commands around.
Why? What can I do?
the numbering is not bound to the parameter number; it's just a  
counter.
calling the macro with two arguments ->
  \iffirstargument  is true
  \ifsecondargument is true
  \ifthirdargument  is false
But why *does it work* without the TABLE commands??
If it would be true (or at least the reason for my problem) what you  
wrote, the following should work:

\def\TestCmd{\dodoubleempty\doTestCmd}
\def\doTestCmd[#1][#2]#3{\bTR\bTD #3
     \ifsecondargument
         \iffirstargument\hfill (#1)\fi
         \eTD \bTD
         3(#1.#2.#3)
     \else
         \iffirstargument\hfill (#1)\fi
         \eTD \bTD
         2(#1/#2/#3)
     \fi
     \eTD\eTR
}

But there I get only a
! Incomplete \iftrue; all text was ignored after line 63.
<inserted text>
                 \fi
