# Incorrect vertical line spacing after changing font size in table

I would like to change the font size of a parragraph in a table cell. If I do not put \par at the end of the parragraph it does not do the correct line spacing. However, if I put it, I get an anoying white line at the bottom of the cell.

Here is an example with no "\par"

\begin{tabular}{m{0.50\textwidth}c}
{\footnotesize Bla bla bla bla bla bla bla bla bla bla
bla bla bla bla bla.} & C\\
{\footnotesize Bla bla bla bla bla bla bla bla bla bla
bla bla bla bla bla.}&C\\
{\footnotesize Bla bla bla bla bla bla bla bla bla bla
bla bla bla bla bla.}&A\\
\end{tabular}


... the result with incorrect linespacing

... the result with the anoying bottom line that prevents the second column to be vertically centered or results in an too large vertical space before the last \hline

Please always post complete documents, but here just remove the {...} around your text and just have
\footnotesize

\begin{tabular}{>{\footnotesize}m{0.50\textwidth}c}
