How do I draw my table with the column lines only in the first row? Here's a MWE of my code:

\documentclass[12pt,a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage{float}
\usepackage[table]{xcolor}

\begin{document}
    \begin{table}[H]
        \centering
        \caption{Data of subways in Fortal city}
        \rowcolors{1}{gray!20}{white}
        \begin{tabular}{c|c|c|c}
            \hline
            Line    & Extension & Stations  & Vehicle type \\
            \hline
            South   & 24,1 km   & 19        & Electric \\
            West    & 19,5 km   & 10        & VLT a diesel \\
            Parangaba-Mucuripe  & 13,2 km   & 10    & VLT a diesel \\
            East    & 7,3 km    & 11        & VLT a diesel \\
            \hline
        \end{tabular}
    \end{table}
\end{document}

What I'd like to achieve:

table with column lines only in the first row

I removed the columns in my tabular agument but I drew them back, only in the header, using multicolumn{1}{c|}{text}

Here's the full working code:

\documentclass[12pt,a4paper]{article}
\usepackage{float}
\usepackage[table]{xcolor}


\begin{document}
    \begin{table}[H]
        \centering
        \caption{Data of subways in Fortal city}
        \rowcolors{1}{gray!20}{white}
        \begin{tabular}{cccc}
            \hline
            \multicolumn{1}{c|}{Line}    & \multicolumn{1}{c|}{Extension} & \multicolumn{1}{c|}{Stations}  & Vehicle type \\
            \hline
            South   & 24,1 km   & 19        & Electric \\
            West    & 19,5 km   & 10        & VLT a diesel \\
            Parangaba-Mucuripe  & 13,2 km   & 10    & VLT a diesel \\
            East    & 7,3 km    & 11        & VLT a diesel \\
            \hline
        \end{tabular}
    \end{table}
\end{document}

Notice that for this particular problem I don't need to draw a column c| in the last column. Otherwise it'd turned into a border, which I don't want to happen.

Furthermore, to avoid always writing multicolumn{1}{c|}{text} I defined a new command \topr{} as \newcommand{\topr}[1]{\multicolumn{1}{c|}{#1}} which spare me to write fixed values. So the improved code turned out like this:

\documentclass[12pt,a4paper]{article}
\usepackage{float}
\usepackage[table]{xcolor}
\newcommand{\topr}[1]{\multicolumn{1}{c|}{#1}}

\begin{document}
    \begin{table}[H]
        \centering
        \caption{Data of subways in Fortal city}
        \rowcolors{1}{gray!20}{white}
        \begin{tabular}{cccc}
            \hline
            \topr{Line}    & \topr{Extension} & \topr{Stations}  & Vehicle type \\
            \hline
            South   & 24,1 km   & 19        & Electric \\
            West    & 19,5 km   & 10        & VLT a diesel \\
            Parangaba-Mucuripe  & 13,2 km   & 10    & VLT a diesel \\
            East    & 7,3 km    & 11        & VLT a diesel \\
            \hline
        \end{tabular}
    \end{table}
\end{document}

calstable

Here is your table type setted using the package cals. As you will find, all rules are visible, and there are no white lines between rules and colours. However, I wold recommend typesetting a classic booktable tabular, without vertical rules, and without any gray shading, see below.

I have defined some shortcuts to reduce coding.

Compared to your original, I have removed side bearing (the left padding in first column and the right padding in the last column, which his customary for academic tables. In addition, I have right aligned the column with figures, but moved the figures to the centre of the column by 1.25em. I also moved the "km" to the column heading. If you prefer one line headings, just increase the column with by some pt.

\newcommand{\rl}{\hspace*{1.25em}}

Classic booktable style tabular

Here I have modified @Levy's code, but made several changes:

  1. Using tabulary for best fitting column with
  2. Used booktabs for correctly spaced rules
  3. Removed side bearing (@{})
  4. Gray shading removed
  5. Columns and headers similar alignment
  6. Small caps header

\documentclass[12pt,a4paper]{article}
\usepackage{booktabs, caption, tabulary}

\begin{document}
    \begin{table}[!tb]
        \small\sffamily\centering
        \caption{Data of subways in Fortal city}
        \begin{tabulary}{\linewidth}{@{}LRRC@{}}
            \toprule
            \textsc{line}    & \textsc{extension\linebreak(km)} & \textsc{stations}  & \textsc{vehicle type}\\
            \midrule
            South   & 24,1   & 19        & Electric \\
            West    & 19,5  & 10        & VLT a diesel \\
            Parangaba-Mucuripe  & 13,2 & 10    & VLT a diesel \\
            East    & 7,3   & 11        & VLT a diesel \\
            \bottomrule
        \end{tabulary}
    \end{table}
\end{document}

With {NiceTabular} of nicematrix, you put a instruction \Block{*-*}{} to say that you don't want the vertical rules to be drawn any longer and that's all.

\documentclass[12pt,a4paper]{article}
\usepackage{float}
\usepackage{nicematrix}

\begin{document}
\begin{table}[H]
\centering
\caption{Data of subways in Fortal city}
\begin{NiceTabular}{c|c|c|c}
\CodeBefore
  \rowcolors{1}{gray!20}{}
\Body
    \hline
    Line    & Extension & Stations  & Vehicle type \\
    \hline
    \Block{*-*}{}
    South   & 24,1 km   & 19        & Electric \\
    West    & 19,5 km   & 10        & VLT a diesel \\
    Parangaba-Mucuripe  & 13,2 km   & 10    & VLT a diesel \\
    East    & 7,3 km    & 11        & VLT a diesel \\
    \hline
\end{NiceTabular}
\end{table}
\end{document}
