gb4e formatting for linguistic examples

Question

I am writing my PhD in Linguistics and I have a lot of examples extracted from the data. I'm using gb4e for numbered examples and glossing. A standard example looks like this:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{gb4e}

\begin{document}
\begin{exe} 
\ex
\gll Reece\textsubscript{1}: this is an example \emph{trên} Internet, \\
\hspace{0cm} \hspace{0cm} \hspace{0cm} \hspace{0cm} \hspace{0cm} on \\
\glt \hspace{1cm} ‘This is an example on the internet’ \\
\hspace*{\fill} (SpeakerA.SpeakerB.0906, 0:37.6 - 0:42.8) 
\label{ex:internet}
\end{exe}
\end{document}

However as I have multiple lines from the transcripts and wanted them to line up, I tried to put them in a tabular environment. This seems to work fine for one example, but when I have 2 next to each other, the \hspace line is all messed up and breaks into multiple places. The example number also somehow got moved to the middle, rather than at the beginning of the example as in the standard example above. Could someone familiar with the package help me with:

1. getting the \hspace line in the right place, and
2. get the example number back to where it should be (as in the standard example)?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{gb4e}

\begin{document}
\begin{exe} 
\ex
\begin{tabular}{l l}
   John\textsubscript{2}:  & $\emptyset$ you want to go to the zoo or Questacon? \\
                            & zoo see the animals. \\
\end{tabular}
\hspace*{\fill} (John.Mary.0709, 09:20.1 - 9:30.5) 
\label{ex:aux}
\end{exe}

\begin{exe} 
\ex
\begin{tabular}{l l}
   Mary\textsubscript{2}:  & you $\emptyset$ going there for nothing, \\
                            & because he is a man. \\
    Rosie\textsubscript{1}:   & He $\emptyset$ not giving standard.\\

\end{tabular}

\hspace*{\fill} (Mary.Rosie.0102, 2:12.3 - 3:32.1) 
\label{ex:aux4}
\end{exe}
\end{document}

I'm not sure if this is what you want, but since you're not really glossing examples word by word, you can group sets of words together with {...} and this will line them up without needing to use tabular. The gb4e macros allow up to 3 aligned lines out of the box: \gll gives you two lines; \glll gives you three lines. You should not try to line up the \glt line; that's not what it's for. To get more lines you could use the technique shown here: Align glosses in more than one language with gb4e to add an extra line (or more in principle). But if you have more lines, then ExPex might be better at this.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{gb4e}
\newcommand\sub{\textsubscript}

\begin{document}
\begin{exe} 
\ex
\glll {Reece\sub{1}:} {this is an example} {\emph{trên} Internet,} \\
 {} {} on {}\\
 {} {‘This is an example} {on the internet’}\\

\hfill (SpeakerA.SpeakerB.0906, 0:37.6 - 0:42.8) 
\label{ex:internet}
\end{exe}

\begin{exe} 
\ex
\gll John\sub{2}:  {$\emptyset$ you want to go to the zoo or Questacon?} \\
   {} {zoo see the animals.} \\

\hfill(John.Mary.0709, 09:20.1 - 9:30.5) 
\label{ex:aux}
\end{exe}

\begin{exe} 
\ex
\glll
   {Mary\sub{2}:}  {you $\emptyset$ going there for nothing,} \\
        {}           {because he is a man. }\\
    {Rosie\sub{1}:}   {He $\emptyset$ not giving standard.}\\

\hfill (Mary.Rosie.0102, 2:12.3 - 3:32.1) 
\label{ex:aux4}
\end{exe}
\end{document}
