Table header color not working as i want

Question

I want the header of my table to be red but as you can see in the example it is red but also it seems there is a white extra column left to it. I can not seem to figure out why it is there. And how to remove it and get it fully red.

Below example table:

Below the code:

\documentclass[11pt, a4paper]{article}
\usepackage[a4paper,top=2cm,hmargin=2cm,bottom=3cm,]{geometry}

\begin{document}
    \noindent\begin{tabular*}{\columnwidth}{@{\extracolsep{\fill}} |l|l|l|l|l|l|l|}

Could you please make your code a compilable minimal working example (MWE) by adding the docmentclass as well as the relevant packages? — leandriis, May 16 '19 at 13:48

tabular* inserts space between the columns, and that is what you are seeing with the white gaps. Forcing the columns apart just make the table harder to read so simplest is to use a normal tabular — David Carlisle, May 16 '19 at 13:51
@DavidCarlisle i changed it into tabular without the asterisk but then i get the following error: l.156 \noindent\begin{tabular}{\columnwidth} {@{\extracolsep{\fill}} |l|l|l|l... — L00n3y, May 16 '19 at 13:52
@L00n3y that isn't an error message, just a location. You presumably didn't delete the {\textwidth} argument that tabular does not have, — David Carlisle, May 16 '19 at 13:57
@DavidCarlisle oops sorry my mistake. I dont have textwidth in my code — L00n3y, May 16 '19 at 14:00
unrelated to the table but you have \usepackage[T1]{fontenc} and \usepackage{fontspec} use the first if you use pdftex and the second if you use luatex or xetex, never use both. similarly never \usepackage[utf8]{inputenc} with luatex or xetex. — David Carlisle, May 16 '19 at 14:06
@DavidCarlisle thank you it worked! finally it worked, thank you for the suggestion about fontspec i will change it :) — L00n3y, May 16 '19 at 14:07

If you actually want your tabular to have a width equal to the maximal width (which is probably not a good idea), you can use {NiceTabular*} of nicematrix. The built-in command \rowcolor of that environment will color the whole row as expected.

\documentclass[11pt, a4paper]{article}
\usepackage[a4paper,top=2cm,hmargin=2cm,bottom=3cm,]{geometry}
\usepackage{nicematrix}
\begin{document}
    \newcommand{\thead}{\color{white}\large\bfseries\sffamily}
    \arrayrulecolor[RGB]{227,24,24}
    \noindent\begin{NiceTabular}{\columnwidth}{@{\extracolsep{\fill}}llccccc}[colortbl-like,hvlines]
    \rowcolor[RGB]{227,24,24}\thead Nr &\thead IP & \thead TL1 & \thead TL2 & \thead TL3 & \thead TL4 & \thead TL5 \ 
    1. & 1.1.1.1 & 5 & 0 & 1 & 0 & 0\ 
    2. & 1.2.3.4 & 5 & 0 & 0 & 0 & 0\ 
    3. & 5.5.5.5 & 2 & 1 & 1 & 1 & 1\ 
    4. & 95.231.766.33 & 1 & 0 & 0 & 0 & 0\ 
    5. & 115.231.796.313 & 1 & 0 & 0 & 0 & 0\ 
    6. & 115.231.776.313 & 1 & 0 & 0 & 0 & 0\

    17. & 95.231.726.33 & 0 & 0 & 1 & 0 & 0\ 
    18. & 95.231.716.33 & 0 & 0 & 1 & 0 & 0\ 
    \end{NiceTabular}
\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).
