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
Code, edit and compile here:
\begin{table}[H]\begin{center}\begin{tabularx}{0.85\textwidth}{ |X|X|X|X| }\hlineOpAmp & 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 &\\& D & 300.243 &\\\hline\multirow{4}{*}{3} &A& 303.297& \multirow{4}[4]{*}{521.7875} \\& B & 302.068 &\\& C & 300.140 &\\& D & 303.602 &\\\hline\multirow{4}{*}{4} &A& 302.953& \multirow{4}[4]{*}{521.7875} \\& B & 303.153&\\& C & 302.910&\\& D & 302.952&\\\hline\end{tabularx}\end{center}\label{relchan}\end{table}
