从编辑器中删除表时禁用菜单项

Question

我有一个小文本编辑器，允许通过菜单栏插入表格。

当我的表单加载时，我的菜单中唯一启用的内容是＆＃34;插入表＆＃34;。一旦我点击插入表，所有其他菜单项现在都已启用。

我正在尝试做什么，而且当我从编辑器中删除表格时，我想重新禁用表格放在编辑器中时启用的项目。

我到目前为止的代码是：

    private void Form1_Load(object sender, EventArgs e)
    {

        RMIInsertRow.Enabled = false;
        RMIInsertCol.Enabled = false;
        RMIMergeCells.Enabled = false;
        RMISplitCellHoriz.Enabled = false;
        RMIDeleteCells.Enabled = false;
        RMIRowPos.Enabled = false;
        RMIRowHeight.Enabled = false;
        RMIHeaderRow.Enabled = false;
        RMIKeepRowTogether.Enabled = false;
        RMIRowTextFlow.Enabled = false;
        RMICellWidth.Enabled = false;
        RMICellBorderWidth.Enabled = false;
        RMICellBorderColor.Enabled = false;
        RMICellShading.Enabled = false;
        RMICellColor.Enabled = false;
        RMICellVertAlign.Enabled = false;
        RMICellRotateText.Enabled = false;
        RMISelectCurCol.Enabled = false;

    }

    private void RMIInsertTable_Click(object sender, EventArgs e)
    {
        t.TestCommand(test.TABLE_INSERT);

        if (sender == RMIInsertTable)
        {
            RMIInsertRow.Enabled = true;
            RMIInsertCol.Enabled = true;
            RMIMergeCells.Enabled = true;
            RMISplitCellHoriz.Enabled = true;
            RMIDeleteCells.Enabled = true;
            RMIRowPos.Enabled = true;
            RMIRowHeight.Enabled = true;
            RMIHeaderRow.Enabled = true;
            RMIKeepRowTogether.Enabled = true;
            RMIRowTextFlow.Enabled = true;
            RMICellWidth.Enabled = true;
            RMICellBorderWidth.Enabled = true;
            RMICellBorderColor.Enabled = true;
            RMICellShading.Enabled = true;
            RMICellColor.Enabled = true;
            RMICellVertAlign.Enabled = true;
            RMICellRotateText.Enabled = true;
            RMISelectCurCol.Enabled = true;
        }            
    }
