I don't see a relation to XeTeX, thus the mailing list texhash
might be the better choice for this question.
The following example addresses calculates the shift to align
the baseline of the footnote line with the first line of
the tabular. No time for looking at the problem with the overfull \vbox.
\documentclass[12pt]{book}
\usepackage{array}
\usepackage[
a4paper,noheadfoot,nomarginpar,margin=20mm,showframe
]{geometry}
\usepackage{zref-savepos}
\makeatletter
\newsavebox\tl@box
\newcount\c@tlcount
\setcounter{tlcount}{0}
\def\thetlcount{\the\c@tlcount}
\newenvironment*{tltabular}[1]{%
\stepcounter{tlcount}%
\begin{lrbox}{\tl@box}%
\begin{tabular}[t]{|#1|}%
\hline
\zref@savepos
\zref@labelbyprops{tl@b\thetlcount}{posy}%
\ignorespaces
}{%
\hline
\end{tabular}%
\end{lrbox}%
\zref@refused{tl@a\thetlcount}%
\zref@refused{tl@b\thetlcount}%
\dimen@=\dimexpr
\zposy{tl@a\thetlcount}sp-\zposy{tl@b\thetlcount}sp%
\relax
\raisebox{\dimen@}{%
\zref@savepos
\zref@labelbyprops{tl@a\thetlcount}{posy}%
\box\tl@box
}%
}
\begin{document}%
xyz\footnote{%
\begin{tltabular}{l}
abc\\
def\\
ghj\\
klm\\
\end{tltabular}%\\
}
xyz\footnote{%
\begin{tltabular}{l}
abc\\
def\\
ghj\\
klm\\
\end{tltabular}%\\
}
\end{document}%
Yours sincerely
