[Tex/LaTex] Tabularx remove extra padding before row

tabularx

I've got a tabularx containing figures that is set to \textwidth but doesn't occupy whole textwdith and leaves a margin on the left. Specifically:

\begin{tabularx}{\textwidth}{A B C}

% num_web_clicks
\rowcolor{red}\multicolumn{3}{B}{\resizebox{\textwidth}{!}{\input{fig1.pgf}}
\\
\rowcolor{blue}\resizebox{.33\textwidth}{!}{\input{fig2.pgf}}
&\resizebox{.33\textwidth}{!}{\input{fig3.pgf}} 
&\resizebox{.33\textwidth}{!}{\input{fig4.pgf}}\\

\end{tabularx}

Where column types are defined as:

\newcolumntype{C}{>{\raggedleft\arraybackslash}X}
\newcolumntype{B}{>{\centering\arraybackslash}X}
\newcolumntype{A}{>{\raggedright\arraybackslash}X}

Which looks like this:

Why does each row have a margin on the left (red/blue extra space before the row, on the left) and how can I remove it?

Just change

\begin{tabularx}{\textwidth}{A B C}

either to

\begin{tabularx}{\textwidth}{@{}A@{}B@{}C@{}}

or to

\setlength\tabcolsep{0pt}
\begin{tabularx}{\textwidth}{A B C}

[Tex/LaTex] Extra horizontal lines in tabularx package

Don't adjust the width of the X-columns. Rather adjust the column that really want to be different and let the X-columns spread out evenly to fill the remainder:

enter image description here

\documentclass{article}
\usepackage{tabularx,array,booktabs}
\newcolumntype{Y}{>{\centering\arraybackslash}X} % for centering tables in tabularx
\def\tabularxcolumn#1{m{#1}}
\newcommand{\heading}[1]{\bfseries\begin{tabular}{@{}c@{}} #1 \end{tabular}}

\begin{document}

\noindent
\begin{tabularx}{\textwidth}{
    >{\centering}m{.185\linewidth} 
    *{4}{Y} }
  \toprule
  \heading{Components} & \heading{Number} & \heading{Algebra} & \heading{Space and \\shape} & \heading{Statistics \\ and \\ probability} \\
  \midrule

  \bottomrule
\end{tabularx}

Tabularx – Controlling Vertical Padding in Tabularx for Itemized Lists

The enumitem package provides the options before=... and after=... to control what comes before and after the list itself. One can use these options to encase the list in a minipage; this is useful because, by default, any whitespace padding above and below a minipage is eliminated automatically.

As the example below shows, it's actually preferable to use the minipage with the [t] ("top") positinioning specifier, as that will assure that the first line in the first list item will be aligned with lines elsewhere in the table (here: Col0).

\documentclass[12pt,a4paper]{article}
\usepackage{enumitem}
\usepackage{tabularx}

\begin{document}
\noindent % <-- important
\begin{tabularx}{\linewidth}{|l|X|X|}
    \hline
    Col 0 & Col 1 & Col 2\\
    \hline
    abcxyz & 
    \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\relax}X|}{%
    Note the vertical space above and below this cell.}\\
    \hline
    abcxyz & 
    \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\linewidth=\hsize}X|}{%
    \begin{itemize}[nosep,align=left,leftmargin=*,
                    before={\begin{minipage}{\hsize}}, % <-- new
                    after={\end{minipage}}             % <-- new
                   ]
      \item The first item in itemize, note the vertical space above this. 
            A bit more to show.
      \item The second item in itemize, note the vertical space below this.
    \end{itemize}}\\
    \hline
    abcxyz & 
    \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\linewidth=\hsize}X|}{%
    \begin{itemize}[nosep,align=left,leftmargin=*,
                    before={\begin{minipage}[t]{\hsize}}, % <-- with "[t]"
                    after={\end{minipage}}%               % <-- new
                   ]%
      \item The first item in itemize, note the vertical space above this. 
            A bit more to show.
      \item The second item in itemize, note the vertical space below this.
    \end{itemize}}\\
    \hline
  \end{tabularx}
  \hrule
  \begin{itemize}[nosep,align=left,leftmargin=*]
    \item The first item in itemize, note the vertical space above this. A bit more to show.
    \item The second item in itemize, note the vertical space below this.
  \end{itemize}
  \hrule
  \begin{itemize}[nosep,align=left,leftmargin=*] % note use of "\strut" directives
    \item \strut The first item in itemize, note the vertical space above this. A bit more to show.
    \item The second item in itemize, note the vertical space below this.\strut
  \end{itemize}
  \hrule
