Excel 想 insert 一行

EXCEL 想 INSERT 一行, 不知是否 FILE 太大, 不能 INSERT,
出現以下文字, 請問點先可以在中段插入到新的一行 ?

To prevent possible loss of data, Microsoft Office Excel cannot shift nonblank cells off the worksheet.

Try to locate the last nonblank cell by pressing CTRL+END, and delete or clear all in cells between the
last cell and the end of your data. Then select cell A1 and save your workbook to reset the last cell used.

Or, you can move the data to a new location and try again.
