code: func ReadZipWithRowLimit(f *zip.ReadCloser, rowLimit int) (*File, error) {

docs: // ReadZipWithRowLimit() takes a pointer to a zip.ReadCloser and returns a
  // xlsx.File struct populated with its contents.  In most cases
  // ReadZip is not used directly, but is called internally by OpenFile.
