Java CSV/CSV文件中的Delete列 [英] Java- CSV / Delete column in csv file

问题描述

我尝试在Java中删除csv文件中的列.

I try to delete a column in csv file in Java.

例如，我有这个csv文件

for example, I have this csv file

ID   name1   name2   name3
1    hello   hell    hel
2    try     tr      t
3    browser bro     br

我想要下一个操作之后:(删除csvFile，2)它将是:

and I want the after the next operation: (delete csvFile, 2) it will be:

ID   name1   name3
1    hello   hel
2    try     t
3    browser br

我发现只有对行而不是列的操作.

I found only operations that invlove rows and not column.

推荐答案

删除CSV文件中一列的唯一方法是删除整个文件中的标题和该列的信息，即针对其中的每一行.文件.即使您使用第三方库，它也会在内部执行此操作.

The only way to delete a column in a CSV file is to remove the header and the information of this column in the whole file, that is for each row of the file. Even if you use a third party library it will do this internally.
