本文介绍使用Spire.PDF for .NET来设置PDF表格跨页时，重复显示表头行的方法。

namespace RepeatTableHeaderRow
{
    class Program
    {
        static void Main(string[] args)
        {
            //新建一个PDF文档
            PdfDocument pdf = new PdfDocument();

            //添加一页
            PdfPageBase page = pdf.Pages.Add();

            //创建PdfGrid类的对象
            PdfGrid grid = new PdfGrid();

            //设置单元格填充
            grid.Style.CellPadding = new PdfPaddings(1, 1, 1, 1);

            //添加表格列数
            grid.Columns.Add(3);

            //添加表头行及表格数据
            PdfGridRow[] pdfGridRows = grid.Headers.Add(1);            
            for (int i = 0; i < pdfGridRows.Length; i++)
            {
                pdfGridRows[i].Style.Font = new PdfTrueTypeFont(new Font("Arial", 11f, FontStyle.Regular), true);//指定字体
                pdfGridRows[i].Cells[0].Value = "NAME";

            }

            //设置重复表头（表格跨页时）
            grid.RepeatHeader = true;

            //添加数据到表格
            for (int i = 0; i < 60; i++)

                }
            }

            //在PDF页面绘制表格
            grid.Draw(page, new PointF(0, 20));          

            //保存文档
            pdf.SaveToFile("Result.pdf");
            System.Diagnostics.Process.Start("Result.pdf");
        }
