表格用vb制作一个选定图形然后鼠标右键再按R键

您可以使用VB编写一个程序来实现您的需求。下面是一个示例程序，它创建一个表格，并在选中图形时，当您按下鼠标右键再按下R键时，会在控制台输出"选定图形，鼠标右键，按下R键"。

Imports System.Windows.Forms

Public Class Form1
    Inherits Form

    Public Sub New()
        Me.DoubleBuffered = True
        Me.Width = 500
        Me.Height = 500
        Me.BackColor = Color.White
    End Sub

    Protected Overrides Sub OnMouseDown(e As MouseEventArgs)
        MyBase.OnMouseDown(e)
        If e.Button = MouseButtons.Left Then
            Dim rect As New Rectangle(100, 100, 200, 200)
            If rect.Contains(e.Location) Then
                Me.BackColor = Color.LightGray
            Else
                Me.BackColor = Color.White
            End If
        End If
    End Sub

    Protected Overrides Sub OnKeyDown(e As KeyEventArgs)
        MyBase.OnKeyDown(e)
        If e.KeyCode = Keys.R AndAlso e.Modifiers = Keys.Control Then
            If Me.BackColor = Color.LightGray Then
                Console.WriteLine("选定图形，鼠标右键，按下R键")
            End If
        End If
    End Sub

    Public Shared Sub Main()
        Application.Run(New Form1())
    End Sub
End Class

请注意，此示例程序仅在控制台窗口中输出文本，而不是在表格中显示选定图形。如果您需要在表格中显示选定图形，请根据您的具体需求自行修改程序
