如何在同一高度的textFrame中获取两个表

Question

我被告知在textFrame内创建了两个表，因为这可能是使两个表在相同高度彼此交叉的最佳方法。当我填写右侧表格的数据和标题时，它不会延伸到与左侧表格相同高度的底部。即使当我添加更多的AddParagraphs（）时，右表大麦的底部也超过了左表的底部边框，因此使表的高度不均匀。是否有解决方法或其他方式？我希望右表上显示“ ADV完整性”的位置与表的左侧均匀延伸。

我的代码：

            //textFrame for Invoice info
            TextFrame billFrame = section.AddTextFrame();

            billFrame.Height = "5.0cm";
            billFrame.Width = "6.0cm";
            billFrame.RelativeHorizontal = RelativeHorizontal.Margin;
            billFrame.Top = "7.5cm";
            billFrame.MarginRight = "10.0cm";
            billFrame.RelativeVertical = RelativeVertical.Page;
            billFrame.Left = ShapePosition.Left;

            //putting table into the Invoice textFrame
            Table table = billFrame.AddTable();

            table.Borders.Width = 0.75;

            Column column = table.AddColumn(Unit.FromCentimeter(7));
            column.Format.Alignment = ParagraphAlignment.Left;

            //define headers of "Bill To" table
            Row row = table.AddRow();
            row.HeadingFormat = true;
            Cell cell = row.Cells[0];
            row.Shading.Color = Colors.LightGray;
            cell.AddParagraph("Bill To:");
            cell.Format.Font.Bold = true;

            //showing data inside Bill table
            row = table.AddRow();
            cell = row.Cells[0];
            cell.AddParagraph("ADV Integrity");
            cell.AddParagraph("Attn: Wendy Courtright");
            cell.AddParagraph("P.O. Box 1449");
            cell.AddParagraph("Waller, TX 77484");
            cell.AddParagraph("United States");


            //textFrame for Invoice info
            TextFrame invoiceFrame = section.AddTextFrame();
            invoiceFrame.Height = "5.0cm";
            invoiceFrame.Width = "6.0cm";
            invoiceFrame.Left = ShapePosition.Right;

            //adding table inside Invoice textFrame
            table = invoiceFrame.AddTable();
            table.Borders.Width = 0.75;

            column = table.AddColumn(Unit.FromCentimeter(3.5));
            column.Format.Alignment = ParagraphAlignment.Left;

            column = table.AddColumn(Unit.FromCentimeter(3.5));
            column.Format.Alignment = ParagraphAlignment.Left;


            //headers for Invoice table
            row = table.AddRow();
            row.HeadingFormat = true;
            cell = row.Cells[0];
            row.Shading.Color = Colors.LightGray;
            cell.AddParagraph("Date");
            cell.Format.Font.Bold = true;

            cell = row.Cells[1];
            cell.AddParagraph("Invoice");
            cell.Format.Font.Bold = true;

            //defining rows and data inside Invoice table
            row = table.AddRow();

            cell = row.Cells[0];
            cell.AddParagraph("04/30/2020");

            cell = row.Cells[1];
            cell.AddParagraph("2000498");

            row = table.AddRow();

            cell = row.Cells[0];
            row.Cells[0].Format.Alignment = ParagraphAlignment.Left;
            row.Cells[0].Format.Font.Bold = true;
            row.Cells[0].Shading.Color = Colors.LightGray;
            row.Cells[0].MergeRight = 1;
            cell.AddParagraph("Account");

            row = table.AddRow();
            cell = row.Cells[0];
            row.Cells[0].Format.Alignment = ParagraphAlignment.Left;
            row.Cells[0].MergeRight = 1;
            cell.AddParagraph("ADV Integrity");
