I want to add a space after a tabular environement. I tried to use the \vspace comand but it does not work, it adds the space between the first and the second line before the table instead of between the first line and the table itself. Any suggestions?
Here is the code:
\begin{tabular}{||m{0.3\textwidth} | m{0.7\textwidth} ||}
\hline \hline
Instruments and measure set up &
\begin{itemize}
\item Power supply
\item Waveform generator ($f=1\mathrm{kHz}, V_{pp}=0.8943\mathrm{V}$)
\item Oscilloscope
\end{itemize}
\\
\hline
Measured data &
\begin{itemize}
\item Output voltage: $V_o$
\end{itemize}
\\
\hline
Involved variables, measured values and procedure &
Using \textit{Math Mode}, measure the voltage drop amplitude across the $8\mathrm\Omega$ resistor taking into account the $\frac{1}{\sqrt{2}}$ factor of the RMS.\newline
Applying the following formula:
$$ P_o = I\cdot V_{o_{RMS}} = \frac{V_{o_{RMS}}^{2}}{R_L}
= \frac{V_o^{2}}{2\cdot8\mathrm{\Omega}}$$
we obtain the power delivered by the amplifier to the speaker.
\\
\hline \hline
\end{tabular}
\vspace{1cm}
\noindent
Specification: $1\mathrm{W} \le P_o \le 3\mathrm{W}$\\ \\
Measurements:
\begin{itemize}
\item $V_o=\frac{V_{pp}}{2}=\frac{7.68\mathrm V}{2}=3.84$V
\end{itemize}
\noindent
\\
{\Large \textbf{Result:} $P_o=0.92$W}

has no special spacing rules it is just like a big letterX
any space you add with vspace or hspace are unrelated to the tabular you would get the same space if you replaced the tabular byX
or\rule{2cm}{3cm}
or any other tex box. – David Carlisle Jan 15 '17 at 11:16\\
you have in that fragment outside the table are completely wrong and you should start by removing them (they surely make warnings in the log file? then add blank lines where you want to start a paragraph, and then vspace will work as you expect/ – David Carlisle Jan 15 '17 at 11:18
