How to draw two \hline and two vertical line?

Question

I want to draw a table with two \hline and two vertical line. But as shown in the figure, the first vertical line do not cross the two hline. How to solve this problem?

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

\begin{tabular}{c||c||c}
\hline 
1 & 2 & 3 \\ \hhline{=|=|=}
4 & 5 & 6 \\ \hline
7 & 8 & 9 \\ \hline
\end{tabular}

\end{document}

output

Minimize the use of vertical lines in tables. They disturb more than they help. — Svend Tveskæg, Jan 02 '14 at 10:00
+Svend I couldn't disagree more. SOME tables look nice without vertical lines, but there are MANY tables that demand them, and the notion that they should be avoided at all cost is a horrific one that is way too prevalent in the LaTeX community. — Travis Bemrose, Feb 01 '16 at 13:02

As stated in the hhline package documentation, | gives you a vertical line which cuts through a double (or single) hline, whereas # gives a double hline segment between two vlines.

So, to correct your situation (leaving aside the aesthetic issues) simply use, # in place of the | in the argument for \hhline.

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

\begin{tabular}{c||c||c}
\hline 
1 & 2 & 3 \\ \hhline{=#=#=}
4 & 5 & 6 \\ \hline
7 & 8 & 9 \\ \hline
\end{tabular}

\end{document}

You get the following output.

Don't use vertical lines in tables; they disturb more than they help.

\documentclass{article}

\usepackage{booktabs}

\begin{document}

\begin{tabular}{ccc}
\toprule
1 & 2 & 3 \\
\midrule
4 & 5 & 6 \\
\midrule
7 & 8 & 9 \\
\bottomrule
\end{tabular}

\end{document}

It is not the answer to OP's question. – Przemysław Scherwentke Jan 02 '14 at 10:43

@PrzemysławScherwentke I don't agree with you. We've hand a "don't do this" answers with alternative provided before. Since TeX is about typography, it's not wrong to provide typographical alternatives to what OP asks for. See e.g. What's the quickest way to write “2nd” “3rd” etc in LaTeX – yo' Jan 02 '14 at 13:53
Thanks so much! It is beautiful but MMA gives the answer 'to' the question. – Eden Harder Jan 02 '14 at 14:21

For information, in {NiceTabular} of nicematrix, the vertical rules (specified by the symbols | in the preamble) are not interrupted by the double horizontal rules (specified by \hline\hline).

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{c||c||c}
\hline 
1 & 2 & 3 \ \hline\hline
4 & 5 & 6 \ \hline
7 & 8 & 9 \ \hline
\end{NiceTabular}
\end{document}
