I'm having issues trying to align all the text at the top of my cells. Indeed, it looks like because of the \makecell I am using, the text beside is not where it should be. I have tried a lot of suggestions from other questions and sites, but nothing is working. Here is an example of my table and the result. We see the first column is not at the top even if I chose "p{}" in my table.

```
\documentclass{article}

% Language setting
% Replace `english' with e.g. `spanish' to change the document language
\usepackage[english]{babel}

% Set page size and margins
% Replace `letterpaper' with`a4paper' for UK/EU standard size
\usepackage[letterpaper,top=2cm,bottom=2cm,left=3cm,right=3cm,marginparwidth=1.75cm]{geometry}

% Useful packages
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage[colorlinks=true, allcolors=blue]{hyperref}
\usepackage{multirow}
\usepackage{makecell}
\title{Your Paper}
\author{You}

\begin{document}
\begin{tabular}{|p{4cm}|p{5cm}|p{4cm}|}
\hline
\multicolumn{3}{|c|}{Title} \\
\hline

\end{tabular}

\end{document}

```
