I found a really fancy table that I intend to copy but I can't find any information on how to do a similar one:
Help would be very welcome, I'm on a rush!
The package pgfgantt was already mentioned in the comments and is probably the most useful to draw any sort of timed plan that also allows updates to the current date, etc.
However a really simple approach like the table you presented, can also be created with a really simple solution like this:
\documentclass[10pt,border=3mm]{standalone}
\usepackage{booktabs,calc,xcolor}
\newcommand{\Heading}[1]{\multicolumn{1}{@{}c@{}}{#1}}
\newcommand{\timebar}[1]{\multicolumn{#1}{@{}p{#1cm}@{}}{\textcolor{cyan}{\rule[0pt]{#1cm}{10pt}}}}
\begin{document}
\begin{tabular}{@{}l@{}p{1cm}@{}p{1cm}@{}p{1cm}@{}p{1cm}@{}p{1cm}@{}p{1cm}@{}p{1cm}@{}}
\toprule
&\Heading{Jul}&\Heading{Aug}&\Heading{Sep}&\Heading{Oct}&\Heading{Nov}&\Heading{Dec}&\Heading{Jan}\
\midrule
Data Analysis Model & \timebar{3} & & & & \
Development & Validation & & \timebar{3} & & &\
Results' Discussion & & & & \timebar{2} &\
Thesis Writing & & \timebar{5} \
Preparation of Presentation & & & & & & \timebar{2}\
\bottomrule
\end{tabular}
\end{document}
\bar. It might appear in the document elsewhere. Maybe use \Bar instead.
