Importing CSV file as a table in Latex but file too long

Question

I am trying to import a CSV file but the data in the table is too long it goes down till the end of the page and disappears without continuing on the next page.

Here's the file:

\begin{filecontents*}{mode1_with.csv}
Stimulus,Percentage of 'Alpha'
1,95.8
2,90.6
3,98.8
4,97
5,76.4
6,74.8
7,84.8
8,81.8
9,53.6
10,58.4
11,70.8
12,66.8
13,46.6
14,42.8
15,54
16,52
17,34
18,29.2
19,77.8
20,78.8
21,59.8
22,56.4
23,66.2
24,63.8
25,41.6
26,42.8
27,63.6
28,63.4
29,44
30,40.2
31,49.8
32,48.6
33,80.8
34,80.4
35,90.8
36,89
37,66.4
38,61
39,69.4
40,72.4
41,30.8
42,32.4
43,39.4
44,37
45,18.2
46,20.8
47,13.4
48,30.6
49,83
50,78.4
51,87
52,81.4
53,60.2
54,55.2
55,70.8
56,86.4
57,42.8
58,39.6
59,49.6
60,46.8
61,27
62,27.6
63,78
64,89.4
\end{filecontents*}

and this is the code I tried so far:

\usepackage{csvsimple}
\begin{document}
\csvreader[tabular=lrrrr,
    table head=\toprule\bfseries Item
             &\bfseries Alpha category (\%) \\\midrule,
    late after line=\\,late after last line=\\\bottomrule,
    before reading={\catcode`\#=12},after reading={\catcode`\#=6}]%
{mode1_with.csv}{1=\Item,2=\Percentage}%
{\Item & \Percentage}%
\end{document}

Answer 1

You want to use longtable:

\documentclass{article}

\usepackage{csvsimple,longtable,booktabs}
\begin{document}

\csvreader[
  longtable=lrrrr,
  table head=\toprule\bfseries Item &\bfseries Alpha category (\%) \\\midrule,
  late after line=\\,
  late after last line=\\\bottomrule,
  before reading={\catcode`\#=12},after reading={\catcode`\#=6}
]{mode1_with.csv}{1=\Item,2=\Percentage}{\Item & \Percentage} 

\end{document}

If you want the header and the bottom rule to be repeated in each page, use

\documentclass{article}

\usepackage{csvsimple,longtable,booktabs}
\begin{document}

\csvreader[
  longtable=lrrrr,
  table head=
    \toprule\bfseries Item &\bfseries Alpha category (\%) \\ \midrule\endhead
    \bottomrule\endfoot,
  late after line=\\,
  before reading={\catcode`\#=12},after reading={\catcode`\#=6}
]{mode1_with.csv}{1=\Item,2=\Percentage}{\Item & \Percentage}

\end{document}

Answer 2

You need to use a longtable rather than a tabular environment. If you use longtable's native syntax, it's straightforward to retain full control over objects such as header and footer material on every page.

Naturally, as @egreg's parallel answer shows, it's possible to do so using csvreader's syntax as well.

\documentclass{article}
\usepackage{booktabs,csvsimple,longtable}
\begin{document}
\begin{longtable}{lr} 
\toprule
\bfseries Item & \bfseries Alpha category (\%) \\
\midrule \endhead
\bottomrule \endfoot
\csvreader[
    late after line=\\,
    late after last line=,
    before reading={\catcode`\#=12},
    after reading={\catcode`\#=6}]%
    {mode1_with.csv}{1=\Item,2=\Percentage}{\Item & \Percentage}
\end{longtable}
\end{document}
