仅计算特定列中的空白

我有一个列A到X的电子表格。我想审计input是否通过计算空白的数量。 COUNTBLANK需要一个范围，但是我有一些必填字段和非强制字段。 我已经尝试了以下公式：

=COUNTIF((A2, B2, F2, G2, H2, I2, J2, M2, N2, R2, S2, T2, V2, W2), "")但是我得到一个#VALUE错误。

Answer 1

你非常接近：

 =(A2="")+(B2="")+(F2="")+(G2="")+(H2="")+(I2="")+(J2="")+(M2="")+(N2="")+(R2="")+(S2="")+(T2="")+(V2="")+(W2="") 

Answer 2

尝试

 =SUM(COUNTIF(INDIRECT({"A2","B2","F2","G2","H2","I2","J2","M2","N2","R2","S2","T2","V2","W2"}),"")) 

要么

 =SUM(COUNTIF(INDIRECT({"A2:B2","F2:J2","M2:N2","R2:T2","V2:W2"}),"")) 

注意： INDIRECT是一个易失性函数。 有关volatile函数的详细信息，请参阅此 。
