Breaking an hline for header

revtextables

I'm generating a document using Revtex{4-2}, and I'm struggling to create a nice table that's broken columnwise into two halves. The table looks something along the lines of this,

and the source code is this,

\begin{table*}[h!]
    \begin{ruledtabular}
        \centering
        \caption{\label{tab:3} Random table.}   
        \begin{tabular}{cccccc}
            \multicolumn{3}{c}{Oil} & \multicolumn{3}{c}{Solution}\\ 
            Var & $x$ & $y$ & Var & $x$ & $y$\\ 
            \hline
            100 & 12 & 0.45 & 180 & 33 & 0.05\\
            200 & 15 & 0.14 & 240 & 84 & 0.04\\
            300 & 34 & 0.09 & 460 & 96 & 0.02\\
            400 & 58 & 0.02 & 780 & 21 & 0.21\\
            500 & 59 & 0.08 & 920 & 57 & 0.85\\
            600 & 7 & 0.50 & 450 & 56 & 0.96\\
            700 & 26 & 0.05 & 120 & 42 & 0.02\\ 
        \end{tabular}
    \end{ruledtabular}
\end{table*}

I would prefer to avoid vertical lines. Is there a way to add a disconnected hline under the multicolumns containing "Oil" and "Solution"? Something like:

I just don't know how to add the horizontal lines under the two multicolumns.

You mean like this? A ruledtabular is nothing other than a page-wide tabular with double rules, this is simply achieved using a tabularx that is \textwidth wide with double \hlines.

\documentclass{article}
\usepackage{tabularx}
\begin{document}

\newcolumntype{Y}{>{\centering\arraybackslash}X}

\begin{table}[h!]
    \renewcommand{\arraystretch}{1.2}
    \centering
    \caption{\label{tab:3} Random table.}  
    \medskip 
    \begin{tabularx}{\textwidth}{YYYcYYY} \hline\hline
        \multicolumn{3}{c}{Oil} & & \multicolumn{3}{c}{Solution}\\ 
        Var & $x$ & $y$ && Var & $x$ & $y$\\ 
        \cline{1-3} \cline{5-7}
        100 & 12 & 0.45 && 180 & 33 & 0.05\\
        200 & 15 & 0.14 && 240 & 84 & 0.04\\
        300 & 34 & 0.09 && 460 & 96 & 0.02\\
        400 & 58 & 0.02 && 780 & 21 & 0.21\\
        500 & 59 & 0.08 && 920 & 57 & 0.85\\
        600 &  7 & 0.50 && 450 & 56 & 0.96\\
        700 & 26 & 0.05 && 120 & 42 & 0.02\\ \hline
    \end{tabularx}
\end{table}

Just adjust the loading order so that eqparbox comes before arydshln:

Note I have also fixed the markup in your particular comments adding math mode and fixing spacing after an abbreviation dot.

One way is to shift up the skip prior to the mid-height \tabucline with a \\[-1pt]. See below for 2nd approach.

Alternately, if you want the thin line to bisect the thick line, then the approach: \\[-1pt] \tabucline[1 pt]{3-5}\\[-12.5pt]\hline works.
