如何删除使用C＃插入书签的当前列？

Question

我有一个表，我选择了两列并将选择标记为书签？现在如何使用C＃删除它？

我的代码是这样的：

/// <summary>
/// Delete all columns of specific bookmark
/// </summary>
/// <param name="bookmark"></param>
public void DeleteTableColumns(string bookmark)
{
   object oBookmark = bookmark;
   if (doc.Bookmarks.Exists(bookmark)) {
      Range range = doc.Bookmarks.get_Item(ref oBookmark).Range;
      //TODO:to be finished
   }
}

我已经知道如何解决这个问题，这是代码：

/// <summary>
    /// Delete all columns of specific bookmark
    /// </summary>
    /// <param name="bookmark"></param>
    public void DeleteTableColumns(string bookmark)
    {
        object oBookmark = bookmark;
        if (doc.Bookmarks.Exists(bookmark)) {
            object oCount = WdDeleteCells.wdDeleteCellsEntireColumn;
            doc.Bookmarks.get_Item(ref oBookmark).Select();
            app.Selection.Cells.Delete(ref oCount);
        }
    }
