Reject duplicate data entry in a cell range. To allow only unique values in a given range, you can use data validation with a custom formula based on the
=COUNT(UNIQUE(D4:D10)) 首先通过UNIQUE函数进行去重,然后通过COUNT函数计数。 (1)COUNTA 函数计算范围中不为空的单元格的个数。 (2)COUNTA 函数计算包含任何类型的信息(包括错误值和空文本 (""))的单元格。例如,如果区域中包含的公式返回空字符串,COUNTA 函数计算该值。COUNTA 函数不会对空单元格进行计数。
