Excel 如何简化这个庞大的VBA If/Then语句

所以我是vba的新手，这是我第八天使用任何类型的代码，所以我为我在代码中使用的“暴力”方法感到抱歉，我知道它没有效率，必须有更好的方法来做到这一点。这正是我要问的，我如何简化代码？它运行良好，并做它需要做的，但它的庞大和缓慢

'RefDate1=cell K36

Dim RefDate1 As Date

RefDate1 = Sheets("Monthly Status").Range("K36")
If RefDate1 = False Then
Sheets("Monthly Status").Range("K34").ClearContents
Sheets("Monthly Status").Range("K33").ClearContents
Sheets("Monthly Status").Range("K32").ClearContents
Sheets("Monthly Status").Range("K31").ClearContents
Sheets("Monthly Status").Range("K30").ClearContents
Sheets("Monthly Status").Range("K29").ClearContents
Sheets("Monthly Status").Range("K28").ClearContents
Sheets("Monthly Status").Range("K27").ClearContents
Sheets("Monthly Status").Range("K26").ClearContents
Sheets("Monthly Status").Range("K25").ClearContents
Sheets("Monthly Status").Range("K24").ClearContents
Else
Sheets("Monthly Status").Range("K34").Value = (RefDate1 - (7 * 6))
Sheets("Monthly Status").Range("K33").Value = (RefDate1 - (7 * 8))
Sheets("Monthly Status").Range("K32").Value = (RefDate1 - (7 * 9))
Sheets("Monthly Status").Range("K31").Value = (RefDate1 - (7 * 11))
Sheets("Monthly Status").Range("K30").Value = (RefDate1 - (7 * 12))
Sheets("Monthly Status").Range("K29").Value = (RefDate1 - (7 * 19))
Sheets("Monthly Status").Range("K28").Value = (RefDate1 - (7 * 20))
Sheets("Monthly Status").Range("K27").Value = (RefDate1 - (7 * 22))
Sheets("Monthly Status").Range("K26").Value = (RefDate1 - (7 * 23))
Sheets("Monthly Status").Range("K25").Value = (RefDate1 - (7 * 26))
Sheets("Monthly Status").Range("K24").Value = (RefDate1 - (7 * 26))
End If

一个工作表变量将在此处执行。。。。声明后，用变量名（

ws

）交换

工作表（“每月状态”）

的每个实例

简化笨重的 非连续版本 连续（K24:K34）快速版本 或者

    Dim RefDate1 As Date
    With  Sheets("Monthly Status")  'use with to save retyping
        RefDate1 =.Range("K36")
        If RefDate1 = False Then
            .Range("K24:K34").ClearContents

        Else
          Dim v
          v = Array(26, 26, 23, 22, 20, 20, 19, 12, 11, 9, 8, 6)   'set up an array

          Dim x  'and a counter
          With Range("K24")  'start at the top
               For x = 0 To 11  'going down 11 cells
              .Offset(x, 0).Value = (RefDate1 - (7 * v(x)))  'an offset of x rows,zero columns
              Next x
          End With
    End If
    end with

你能解释一下怎么做吗？我知道什么是循环，只是不知道如何在这种情况下使用它。抱歉，我对这张

表格（“每月状态”）.范围（“K24:K34”）.ClearContents

非常陌生。只需一行即可清除该范围。
