If I remove a element such as \@percentage, I can print. But this is not my expectation. I want to show many rows, columns.

A diff generally only works between two (or three) files, so perhaps you could explain more about what you want your output to look like? Please show some short, representative sample input, and the expected output for that input, each within <code> tags. See also How do I post a question effectively? and Short, Self-Contained, Correct Example.

Also, a tip: Instead of including all the code to read from the input, it's much easier for us to test by including the input values in the code, e.g. my @codecs = ("0\n", "0\n"); ..., and your sample code will be shorter.
