以表格格式将数据写入文本文件

Question

到目前为止我有这个:

File dir = new File("C:\\Users\\User\\Desktop\\dir\\dir1\\dir2);
dir.mkdirs();
File file = new File(dir, "filename.txt");
FileWriter archivo = new FileWriter(file);
archivo.write(String.format("%20s %20s", "column 1", "column 2 \r\n"));
archivo.write(String.format("%20s %20s", "data 1", "data 2"));
archivo.flush();
archivo.close();

然而.文件输出如下所示:

我完全不喜欢.

如何为文本文件的输出创建更好的表格格式？

非常感谢任何帮助.

提前致谢!

编辑:修复!

而且,而不是看起来像

    column 1             column 2
      data 1               data 2

我怎么能让它看起来像这样:

column 1             column 2
data 1               data 2

会那样喜欢它.

Answer 1

将\r\n被被评为第二个参数的一部分,因此,它基本上计算所需的空间,就像这样...... 20 - "column 2".length() - " \r\n".length(),但由于第二行没有这一点,它需要较少的空间,并期待错位...

尝试添加\r\n作为基本格式的一部分,例如......

String.format("%20s %20s \r\n", "column 1", "column 2")

这产生类似......

        column 1             column 2
          data 1               data 2

在我的测试中......

我想你正试图以表格格式获取数据.我开发了一个Java库,可以构建更复杂的表,并提供更多自定义.您可以在此处获取源代码.以下是我的库可以创建的一些基本表视图.希望这很有用!
