This may be the solution you are looking for, although it is a bit clumsy. You have to include array package to get option b{} for table alignement.
\documentclass{article}
\usepackage{array}
\begin{document}
\begin{tabular}{b{0.1\linewidth}b{0.8\linewidth}p{0.1\linewidth}}
Figure & & Page \\
1.1.1 & test text text text text text text text text text text text text text text text text text text \dotfill & 10 \\
1.1.2 & line \dotfill & 12 \\
1.1.3 & a lot of text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text \dotfill & 15 \\
\end{tabular}
\end{document}
The thing you have to do is compile the code above, and look for the lines, where the middle column is on multiple lines:

Then insert \newline after the Figure number, so it will move up a line. So in this case the table will look like:
\begin{tabular}{b{0.1\linewidth}b{0.8\linewidth}p{0.1\linewidth}}
Figure & & Page \\
1.1.1\newline & test text text text text text text text text text text text text text text text text text text \dotfill & 10 \\
1.1.2 & line \dotfill & 12 \\
1.1.3\newline\newline & a lot of text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text \dotfill & 15 \\
\end{tabular}
And the final result:

\documentclassand ending with\end{document}. – Steven B. Segletes Sep 27 '14 at 12:17
