Remove whitespace before tabular within textblock*

Question

Could you help me align Text2, within tabular and textblock*, to the baseline of Text1?

Would be much appreciated.

\documentclass{article}
\usepackage[absolute,overlay]{textpos}

\begin{document}
\begin{textblock*}{30mm}(30mm,30mm)
    Text1
\end{textblock*}

\begin{textblock*}{30mm}(30mm,30mm)
\begin{tabular}[t]{@{}l}
    Text2
\end{tabular}
\end{textblock*}

\end{document}

Answer 1

Struts are added in the lines of a tabular. If \arraystretch is not redefined, \strut can be added:

\documentclass{article}
\usepackage[absolute,overlay]{textpos}

\begin{document}
\begin{textblock*}{30mm}(30mm,30mm)
    Text1\strut
\end{textblock*}

\begin{textblock*}{30mm}(30mm,30mm)
\begin{tabular}[t]{@{}l}
    Text2
\end{tabular}
\end{textblock*}

\end{document}

Otherwise:

\documentclass{article}
\usepackage[absolute,overlay]{textpos}

\renewcommand*{\arraystretch}{1.2}

\newcommand*{\arstrut}{%
  \vrule height\arraystretch\ht\strutbox
         depth\arraystretch\dp\strutbox
         width0pt\relax
}

\begin{document}
\begin{textblock*}{30mm}(30mm,30mm)
    Text1\arstrut
\end{textblock*}

\begin{textblock*}{30mm}(30mm,30mm)
\begin{tabular}[t]{@{}l}
    Text2
\end{tabular}
\end{textblock*}

\end{document}

Update: Reverse the correction by moving the tabular block.

\documentclass{article}
\usepackage[absolute,overlay]{textpos}

\renewcommand*{\arraystretch}{1.2}

\begin{document}
\begin{textblock*}{30mm}(30mm,30mm)
    Text1
\end{textblock*}

\begin{textblock*}{30mm}(30mm,30mm)
\settoheight{\dimen0}{Text1}%
\kern\dimen0\relax
\kern-\arraystretch\ht\strutbox\relax
\begin{tabular}[t]{@{}l}
    Text2
\end{tabular}
\end{textblock*}

\end{document}
