When you import from a text or spreadsheet file, the file must have a first row of header information. The second row of the file is the first valid data row. The format of every field in the second row determines the format for the entire column. Any format information from a spreadsheet file gets lost when importing to Base.
从文本文件或电子表格文件导入时，该文件的首行必须包含标题信息。该文件的第二行是第一个有效数据行。第二行中每个字段的格式将确定整列的格式。电子表格文件中的所有格式信息将在导入到 Base 时丢失。
