我是 LaTeX 的新手，目前面临在文档中插入长表格的问题。
我有一张长表格.csv，我希望将其插入到具有多列和一个表格标题的文档中，如上图所示。
这是我的代码：

当我编译代码时收到一条错误消息：
包 pgfplots 错误：抱歉，无法从表 'pgfplotstable.data.csv' 中检索列 'Station'。请检查拼写（或引入名称别名）。
我哪里搞砸了？
答案1
由于您没有指定列分隔符为comma，因此 pgfplots 默认为space字符。因此，它无法读取您的表格。
只需指定它是逗号：col sep=comma,
我引用pgfplotstable手册第 5 页的内容：
/pgfplots/table/col sep=space|tab|comma|semicolon|colon|braces|&|ampersand (initially space)指定用于表格读取的列分隔符。初始选择为空格，表示“至少一个空格”。空格是制表位或空格（换行符始终用于分隔行）。
