It's not really an OS issue, but a text editor issue. In Word, UltraEdit, etc, I can set the tab size. I don't think Notepad allows you to. So if there is an option to set the tab size, just make it bigger.
Alternatively, just open the text file in Excel. Excel will read a tab delimited text file with no issues and the columns will be properly filled in.
