Obeylines and gappto from etoolbox

In order to simplify data entry with as little markup of the data as possible, I am attempting the following:

documentclass{article}



usepackage{etoolbox}



begingroup

    obeylines

    gdefing#1 #2 #3{gappto{tabbody}{% Collect rows of tabular[x] in tabbody

    %% Ignore #1 and/or #2 if empty (= . )

    if.#2

        if.#1

            &&#3\

        else

            #1&&#3\

        fi

    else

        if.#1

            &#2&#3\

        else

            #1&#2&#3\

        fi

    fi

    }%

}

endgroup



%%%%%% This, without the if's works, though it does not do what I need:



begingroup

obeylines

gdefiing#1 #2 #3{gappto{tabbody}{% Collect rows of tabular[x] in tabbody

    #1&#2&#3\

    }%

}

endgroup



begin{document}



begingroup

obeylines

everypar={ing} %<<<--- change to iing and there is no error

a 1 u

b 2 v

. 3 w

d 4 x

e 5 y

f 6 z

endgroup



begin{tabular}{ccc}

    tabbody

end{tabular}



end{document}

I'm getting an unexpected error:

ERROR: Incomplete if; all text was ignored after line 39.



--- TeX said ---

<inserted text> 

            fi 

l.39 ^^I^^Itabbody

I have looked at past queries, but have not thus far found an answer. If I remove all of the if statements from the definition of ing (=iing) the problem goes a way. Quite sure I'm missing something really basic -- something to do with the timing of the expansion of the ifs, but I'm stuck for the moment.

  Why do you need obeylines so many places? Dropping obeylines before the definition of ing allows the file to compile and produces reasonable output.
