Plot a data/Table from Mathematica using `pgfplots`

Question

I use data1 = Table[] in Mathematica 9 (M9) to generate a table of values. The thing is that when I read the data file, there's only one column! How can I plot this data file in LaTeX using pgfplots? Here's a ME

\documentclass[border=1]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.5}
\begin{document}
\begin{tikzpicture}
    \begin{axis}
            \addplot table {TestTable.csv};
     \end{axis}
\end{tikzpicture}
\end{document}

I also tried TestTable.txt instead of .csv but without any success. TestTable.csv is generated in M9 with the following code

Export[NotebookDirectory[] <> "TestTable.csv", data1]

where data1 is defined earlier in M9 is some data e.g. numerical integration or similar. A smaller version of data1 in textform (i.e. TestTable.txt) looks like this

1.1
2.3
3.0
4.1
5.3
6.2
7.3
8.4
9.6
10.3

You can use

\addplot table[x expr=\coordindex,y index=0] {TestTable.csv};

The y values are read from first column which has the index 0 (zeroth column).

Full code:

\documentclass[border=1]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.5}   %% why 1.5? pl. update
\begin{document}
\begin{tikzpicture}
    \begin{axis}
            %\addplot table {TestTable.csv};
            \addplot table[x expr=\coordindex,y index=0] {TestTable.csv};
     \end{axis}
\end{tikzpicture}
\end{document}

The TestTable.csv has the following content:

1.1
2.3
3.0
4.1
5.3
6.2
7.3
8.4
9.6
10.3
