The upper-left cell is the cell that is shared by the column header row and the row header column. 左上角的单元格是由列标题行和行标题列共享的单元格。
You can change the order of the field names in the header row by dragging them to appropriate positions in the current view in the Contacts folder. 可以通过拖动到联系人文件夹中适当位置当前视图中更改顺序标题行中的字段名称。
