Why xlsx.RemoveRow("Sheet1", 2) removes 3rd row not second?

As described in https://github.com/360EntSecGroup-Skylar/excelize/blob/master/rows.go#L341

// RemoveRow provides a function to remove single row by given worksheet name
// and row index. For example, remove row 3 in Sheet1:
//
// xlsx.RemoveRow("Sheet1", 2)

Ok, answer myself.
Because row argument probably is not Excel row number, but zero-based slice row number.

Counter-intuitive as for me :(
