Hi what I'm trying to do is getting an "empty" column on a table.

Having an empty row is easy by adding a `\hline`

twice. Like here:

```
\documentclass[12pt]{article}
\begin{document}
\begin{tabular}{|c|c|c|c|}
\hline
& headline1 & headline2 & headline3 \\
\hline
\hline % <-- extra one giving my an "empty" row
row1 & a & b & c \\
\hline
row2 & d & e & f \\
\hline
row3 & g & h & i \\
\hline
\end{tabular}
\end{document}
```

Is there a way of having the same on a column ? E.g. between "row1" and "a".

I tried to ad an additional `|`

on the definition (`\begin{tabular}{|c||c|c|c|}`

), but the horizontal lines are displayed (due to `\hline`

causes a line on the whole width of the table)

```
\documentclass[12pt]{article}
\begin{document}
\begin{tabular}{|c||c|c|c|} %<-- change here
\hline
& headline1 & headline2 & headline3 \\
\hline
\hline
row1 & a & b & c \\
\hline
row2 & d & e & f \\
\hline
row3 & g & h & i \\
\hline
\end{tabular}
\end{document}
```

What I want to have is this output, but without the red circled borders (I want to have it like the green one):

This is how the column should appear:

You can use the

`hhline`

package.
