To copy to clipboard, switch view to plain text mode

It seems like your file containing tab separated entries is broken. Make sure that you don't have 2 tabs between entries in the line.

You can also try to fix your buffer string in the code:

buffer.replace(QRegExp("[\t]+"), "\t");

buffer.replace(QRegExp("[\t]+"), "\t");

To copy to clipboard, switch view to plain text mode 

But if you don't want to get into some troubles later on, you should place each string in a seperate cell, hence using a table would be helpful.

This is a classics problem while using tabs in text file, a lasting solution is split each row into individual cells, as Rachol suggested.
