Tables in LyX: too much vertical space in cell with fixed column width and wrapped text

In a cell with fixed column width and wrapped text in a table - the table is generated entirely in LyX, rather than LaTeX - there is too much vertical space in that cell. Image below; problem highlighted in yellow. Does anyone have any thoughts on how to deal with this? I've tried line spacing (single) and modifying the height of the cell (impossible).

(My LyX tables are quite pretty now - thanks mostly to the expertise of everyone on this forum - but this issue is still bothering me.)

Edit: this is what LaTeX is apparently doing in the background:

\begin{singlespace}
\noindent \begin{center}
\begin{tabular}{lc}
\toprule
\textbf{Test XYZ} & \textbf{p-value}\tabularnewline
\midrule
Statistic A & 0.00\tabularnewline
Statistic B & 0.00\tabularnewline
Statistic C & 0.00\tabularnewline
\midrule
\multicolumn{2}{>{\raggedright}p{0.75\textwidth}}{\begin{singlespace}
\noindent \raggedright{}\textcolor{black}{\footnotesize{}Lorem ipsum
dolor sit amet, consectetur adipiscing elit. Donec mollis est libero,
sed vehicula erat tempor eget. Morbi justo justo, mattis ut elit tristique,
iaculis ornare sapien. Nulla tristique eros id justo pulvinar lacinia. }
\end{singlespace}
}\tabularnewline
\bottomrule
\end{tabular}
\par\end{center}
\end{singlespace}


Thanks a million!

• Welcome to TeX SX! Could you post a full compilable code for this table? Jun 13 '18 at 9:15
• @Bernard This is fully generated in LyX -- i.e. Insert Table etc.; then a right-click into the cell the width of which I want to fix, and so on. I can add a Lyx file rather than code? Jun 13 '18 at 9:16
• No idea. I don't know Lyx, so I can't help in this respect, but the reason for this unwanted spacing lies in the LaTeX code which is behind. Jun 13 '18 at 9:19
• @Bernard I've added the LaTeX code Jun 13 '18 at 9:24
• @oceansize: The unwanted vertical white space is caused by the singlespace environment inside the multicolumn. Jun 13 '18 at 9:29

The extra vertical white space is caused by the singlespace environment inside the multicolumn command. You can safely remove this environment to obtian the following output:
