\documentclass[a4paper,11pt]{article}
\usepackage{csvsimple}
\begin{document}
\csvreader[head to column names,separator=semicolon]{test.csv}{}
{\LASTNAME \\}
\end{document}
test.csv的内容：

问题在于test.csv文件的格式。条目包含一个额外的结尾;。要解决这个问题，可以
--在标题中添加一个额外字段
UID;CASID;USERNAME;LASTNAME;FIRSTNAME;MAIL;VALID;CIV;MIDDLENAME;URL;LANGUEID;PHONE;FAX;DATE;Arrival date;Departure date;Number of accompanying persons;Institution;Mailing Address;Country of organization;Laboratory;STATUS;extra
1;1;user;doe;joe;[email protected];;;;;;;;;;;;college;;;;;
--删除;条目末尾的
UID;CASID;USERNAME;LASTNAME;FIRSTNAME;MAIL;VALID;CIV;MIDDLENAME;URL;LANGUEID;PHONE;FAX;DATE;Arrival date;Departure date;Number of accompanying persons;Institution;Mailing Address;Country of organization;Laboratory;STATUS
