【问题描述】:
假设单元格 A5 中有以下公式:=SUM(A1:A5)
我想用 VBA 给这个公式加 1 使它成为=SUM(A1:A5) + 1
我尝试过Range("A5") = Range("A5") + 1,但这只是将其更改为硬编码数字而不是公式+ 1。我该如何解决这个问题?
感谢您的帮助!

类似这样的东西,包括对公式存在的测试
If Range("A5").HasFormula Then Range("A5").Formula = Range("A5").Formula & "+1"
更新:要在大量单元格上快速执行此操作,自动更新您应该使用的公式variant arrays
更改 strAdd = "+1" 为您的后缀附加

【讨论】:
rngArea.Formula = rngArea.Formula & strAdd。我将更改此行以避免不必要的外观差异
Range("A5").Formula = Range("A5").Formula & "+1"
