This is a mini-example of a problem text I have:

\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{booktabs}
\begin{document}

\begin{table}[!h]\centering
\caption{Bla bla}
\begin{tabular}{c|ccc|ccc}\\ \toprule
& \multicolumn{3}{|c} {bla}
& \multicolumn{3}{|c} {bla} \\ \midrule
$H$ & $2 \times 2$ & $3 \times 3$ & $4 \times 4$
& $2 \times 2$ & $3 \times 3$ & $4 \times 4$ \\ \midrule
1.0 & 7.07 & 12.5 & 18.5 & 0.77 & 0.77 & 0.80 \\
2.0 & 7.78 & 15.0 & 23.6 & 0.56 & 0.59 & 0.64 \\
5.0 & 8.64 & 18.1 & 30.3 & 0.31 & 0.34 & 0.39 \\
10.0 & 9.04 & 19.6 & 34.1 & 0.18 & 0.20 & 0.23 \\
\bottomrule
\end{tabular}\label{Tab:stst}
\end{table}
\end{document}

How do I get rid of the vertical bar at the top?

It's there because you have added a blank line before \toprule. If you
remove the \\ and instead use spacing after the caption it should be OK.

.......................................
\begin{table}[!h]\centering
\caption{Bla bla}
\medskip
\begin{tabular}{c|ccc|ccc} \toprule
.......................................

Parallel lines never meet, unless you bend one or both of them.
