至今还未解决，无奈只能多增加一列，其他行的控件就要跨2列了~
部分代码：
             //Get the culture property of the thread.
             CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
             //Create TextInfo object.
             TextInfo textInfo = cultureInfo.TextInfo;
             //名称
             Label nameLb = new Label();
             nameLb.Name = Tag_Name;
             nameLb.Text = textInfo.ToTitleCase(Tag_Name);
             nameLb.Anchor = (AnchorStyles)(AnchorStyles.Right);
             TextBox nameBox = new TextBox();
             nameBox.Name = Tag_Name;
             tlp.SetColumnSpan(nameBox, 2);
             nameBox.Anchor = (AnchorStyles)(AnchorStyles.Left | AnchorStyles.Right);
             //更新日期
             Label modityDateLb = new Label();
             modityDateLb.Name = Tag_ModifyDate;
             modityDateLb.Text = textInfo.ToTitleCase(Tag_ModifyDate);
             modityDateLb.Anchor = (AnchorStyles)(AnchorStyles.Right);
             DateTimePicker dtp = new DateTimePicker();
             tlp.SetColumnSpan(dtp,2);
             tlp.Anchor = (AnchorStyles)(AnchorStyles.Left | AnchorStyles.Right);
             //描述
             Label descLb = new Label();
             descLb.Name = Tag_Description;
             descLb.Text = textInfo.ToTitleCase(Tag_Description);
             descLb.Anchor = (AnchorStyles)(AnchorStyles.Right);
             TextBox descBox = new TextBox();


             descBox.Name = Tag_Description;
             tlp.SetColumnSpan(descBox, 2);
             descBox.Anchor = (AnchorStyles)(AnchorStyles.Left | AnchorStyles.Right);
             //版本
             Label versionLb = new Label();
             versionLb.Name = Tag_Version;
             versionLb.Text = textInfo.ToTitleCase(Tag_Version);
             versionLb.Anchor = (AnchorStyles)(AnchorStyles.Right);
             TextBox versionBox = new TextBox();
             versionBox.Name = Tag_Version;
             tlp.SetColumnSpan(versionBox, 2);
             versionBox.Anchor = (AnchorStyles)(AnchorStyles.Left | AnchorStyles.Right);
             //子流程
             Label subflowLb = new Label();
             subflowLb.Name = Tag_SubFlows;
             subflowLb.Text = textInfo.ToTitleCase(Tag_SubFlows);
             subflowLb.Anchor = (AnchorStyles)(AnchorStyles.Right);
             TextBox subflowBox = new TextBox();
             subflowBox.Name = Tag_SubFlows;
             subflowBox.Text = "(**)";
             subflowBox.Anchor=(AnchorStyles)(AnchorStyles.Left|AnchorStyles.Right);
             Button subflowButton = new Button();
             subflowButton.Text = "...";
             subflowButton.Anchor = (AnchorStyles)(AnchorStyles.None);
