1、首先在开发工具中打开VBA编辑器

2、在单元格区域当中输入一些内容作为例子

3、在VBA编辑器中插入模块

4、在模块当中输入如下代码,然后运行
Sub 选择粗线边框之单元格()
On Error Resume Next
Dim rng As Range, rg As Range
For Each rng In ActiveSheet.UsedRange
If rng.Borders(xlEdgeRight).Weight = xlMedium And rng.Borders(xlEdgeTop).Weight = xlMedium _
And rng.Borders(xlEdgeBottom).Weight = xlMedium And rng.Borders(xlEdgeLeft).Weight = xlMedium Then
If rg Is Nothing Then
Set rg = rng
Else
Set rg = Application.Union(rg, rng)
End If
End If
Next
rg.Select
End Sub

5、使用快捷键Alt+F8调出运行宏窗口,然后单击“执行”按钮,可以看到所有加粗实线边框之单元格已被选中
