Importing CSV table - Error [closed]

Question

I am new to LaTeX and am compiling a document right now using TeXworks. I am trying to create CSV tables into my document right now, and although I succeed in between I must have some small bug in the code which I just cannot spot (trust me I looked for hours).

My code is the following:

\documentclass[9pt]{article}

% Load packages

%************************************************************

\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{geometry}
    \geometry{verbose,tmargin=1in,bmargin=1in,lmargin=0.75in,rmargin=0.75in}
\usepackage{textcomp}
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage{subfig}
\usepackage{rotating}
\usepackage{datatool} % Allows importing tables
\usepackage{enumerate} % Allows latin I option

\renewcommand{\tabcolsep}{2pt}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}



\DTLsetseparator{,}
\DTLloaddb{tarea}{table_test.csv}

\begin{table}
  \caption{Area}
  \centering
  \DTLdisplaydb{tarea}
\end{table}

\end{document}

Latex gives me the following errors:

Error 1

undefined
34
! Argument of \@dtl@trim has an extra }.
<inserted text> 
                \par 
l.34 \beginstable}

Error 3

Package geometry Warning: The marginal notes overrun the paper.
     Add 21.7975pt and more to the right margin.

May I suggest you to use pgfplotstable? It works great with CSV files and gives you a lot of control. Here's a nice example:

\documentclass[oneside]{article}

\usepackage{pgfplotstable}
% recommended:
\usepackage{booktabs}
\usepackage{array}
\usepackage{colortbl}

\pgfplotstableset{col sep=comma}

\begin{document}



\begin{table}
\centering
\pgfplotstabletypeset[%
    % Sort the values 
    sort, sort key=error2,
    %
    % The columns to be printed
    columns={dof,error1,{grad(log(dof),log(error2))}},
    %
    % Columns styles
    columns/error1/.style={
        % Name
        column name=$L_2$,
        % Notation and padding
        sci,sci zerofill, sci subscript,
        precision=3},
    columns/dof/.style={
        sci, sci sep align, 
        column name=\textsc{Dof}},
    columns/{grad(log(dof),log(error2))}/.style={
        column name=slopes $L_2$,
        fixed, fixed zerofill,
        % Align decimal deparators
        dec sep align, 
        precision=1},
    %
    % Some colors.
    every even row/.style={
        before row={\rowcolor[gray]{0.9}}},
    every head row/.style={
        before row=\toprule,after row=\midrule},
    every last row/.style={
        after row=\bottomrule},
        ]{data.csv}
\end{table}

\end{document}
