You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: error.go
    path of file: ./repos/podman/vendor/github.com/BurntSushi/toml
    
    the code of the file until where you have to start completion: package toml

import (
	"fmt"
	"strings"
)

// Par
    
func (pe ParseError) column(lines []string) int {
	var pos, col int
	for i := range lines {
		ll := len(lines[i]) + 1 // +1 for the removed newline
		if pos+ll >= pe.Position.Start {
			col = pe.Position.Start - pos
			if col < 0 { // Should never happen, but just in case.
				col = 0
			}
			break
		}
		pos += ll
	}

	return col
}
