  key='download_cell_limit',

  # 表格限制的大小，行数 * 列数。加一个0即可，修改后可下载的行数变成100万

  default=10000000,

  type=int,

  help=_t('A limit to the number of cells (rows * columns) that can be downloaded from a query '

          '(e.g. - 10K rows * 1K columns = 10M cells.) '

          'A value of -1 means there will be no limit.'))

def get_deprecated_download_cell_limit():

  """Get the old default"""

  # 表格的大小除100，就是行数，100是列数

  return DOWNLOAD_CELL_LIMIT.get() / 100 if DOWNLOAD_CELL_LIMIT.get() > 0 else DOWNLOAD_CELL_LIMIT.get(
