I have been working a while with LateX now and I love it! I came across one problem though.
I want to create this table: Everything works except that one missing vertical line in row 1! I already tried to search for the error and read multiple tutorials but none seem to help me

Here is the code for the table:
Code: Select all
\begin{table}[H]
\begin{center}
\begin{tabularx}{0.85\textwidth}{ |X|X|X|X| }
\hline
OpAmp & OpAmp-Output & Output voltage [mv] &Mean STD [$\mu V$] \\
\hline
\multirow{4}[4]{*}{1} &A& 301.972 & \multirow{4}[4]{*}{521.7875} \\
& B & 304.959 \\
& C & 301.172 \\
& D & 305.863 \\
\hline
\multirow{4}{*}{2} &A& 301.758 & \multirow{4}[4]{*}{521.7875} \\
& B & 306.230 &\\
& C & 300.732 &\\
