# How I merge the cells?

I put this code in LaTeX:

\begin{table}[H]

\begin{tabularx}{\linewidth}{l*{4}{>{\centering\arraybackslash}X}}

\toprule

Ensaio & Medi\c{c}\~{o}es do comprimento do fio (cm) & Incerteza associada (cm)\\

\midrule

1 & 48,80 & 0,05\\

2 & 48,80\\

3 & 48,70\\

M\'{e}dia & 48,77\\

\bottomrule

\end{tabularx}

\end{table}


I wanna the numbers and the text of first column in the center. How I make this?

• You've posted some questions already, you should know how to mark the code up by now. Also most of your questions have acceptable answers, but unfortunately, you did not accept a single one. This is not how TeX.SX works. Accepting and upvoting means appreciating the work done by many users here

• you have declared a 5 column table but no row has more than 3 columns, it is hard to guess the intended layout. Also no one can run your fragment to see the issue, please always make your examples complete documents. Apr 11 '16 at 22:13
• use c not l for a centred column. Apr 11 '16 at 22:14

I would do it this way. Note you can use accented letters from your keyboard, as all systems nowadays understand UTF8:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{amsmath,tabularx, float, booktabs}
\renewcommand{\tabularxcolumn}[1]{>{\centering\arraybackslash}m{#1}}

\begin{document}

\begin{table}[H]
\begin{tabularx}{\linewidth}{c*{2}{X}}
\toprule
Ensaio & Medições do comprimento do fio (cm) & Incerteza associada (cm) \\
\midrule
1 & 48,80 & 0,05 \\
2 & 48,80\\
3 & 48,70\\
Média & 48,77\\
\bottomrule
\end{tabularx}
\end{table}

\end{document}
