表格能夠直觀的傳達數據信息,使信息顯得條理化,便於閱讀同時也利於管理。那在PDF類型的文檔中如何來添加表格並且對錶格進行格式化操作呢?使用常規方法直接在PDF中添加表格行不通,那我們可以在藉助第三方組件的情況下來實現。本篇文章中將介紹如何正確使用組件Free Spire.PDF for .NET添加表格到PDF。該組件提供了兩個類PdfTable和PdfGrid用於創建表格,在進行代碼編輯前,需先安裝,添加Spire.PDF. dll到項目程序集中,同時添加到命名空間。下面是兩種方法來添加表格的全部代碼,供參考。
一、通過PdfTable類來創建表格
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Tables;
using Spire.Pdf.Graphics;
using System.Data;
namespace DrawTable1_PDF
{
class Program
{
static void Main(string[] args)
{
//創建一個PdfDocument類對象並向文檔新添加一頁
PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add();
//創建一個PdfTable對象
PdfTable table = new PdfTable();
//設置字體
table.Style.DefaultStyle.Font = new PdfTrueTypeFont(new Font("Arial Unicode MS", 9f), true);
table.Style.HeaderStyle.Font = new PdfTrueTypeFont(new Font("Arial Unicode MS", 9f), true);
//創建一個DataTable並寫入數據
DataTable dataTable = new DataTable();
dataTable.Columns.Add("產品類型");
dataTable.Columns.Add("產品編號");
dataTable.Columns.Add("採購數額(件)");
dataTable.Columns.Add("所屬月份");
dataTable.Rows.Add(new string[] { "A", "00101", "35", "7月"});
dataTable.Rows.Add(new string[] { "B", "00102", "56", "8月"});
dataTable.Rows.Add(new string[] { "C", "00103", "25", "9月"});
//填充數據到PDF表格
table.DataSource = dataTable;
//顯示錶頭(默認不顯示)
table.Style.ShowHeader = true;
//在BeginRowLayout事件處理方法中註冊自定義事件
table.BeginRowLayout += Table_BeginRowLayout;
//將表格繪入PDF並指定位置和大小
table.Draw(page, new RectangleF(0, 60, 200, 200));
//保存到文檔並預覽
doc.SaveToFile("PDF表格_1.pdf");
System.Diagnostics.Process.Start("PDF表格_1.pdf");
}
//在自定義事件中設置行高
private static void Table_BeginRowLayout(object sender, BeginRowLayoutEventArgs args)
{
args.MinimalHeight = 10f;
}
}
}
運行程序生成文件(可在該項目文件下bin>Debug查看)

二、通過PdfGrid類來添加表格
using Spire.Pdf;
using System.Drawing;
using Spire.Pdf.Grid;
using Spire.Pdf.Graphics;
using Spire.Pdf.Tables;
namespace DrawTable_PDF
{
class Program
{
static void Main(string[] args)
{
//創建一個PdfDocument類對象,並新添加一頁到PDF文檔
PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add();
//創建一個PdfGrid對象
PdfGrid grid = new PdfGrid();
//設置單元格邊距和表格默認字體
grid.Style.CellPadding = new PdfPaddings(1, 1, 1, 1);
grid.Style.Font = new PdfTrueTypeFont(new Font("Arial Unicode MS", 9f), true);
//添加一個5行6列表格到新建的PDF文檔
PdfGridRow row1 = grid.Rows.Add();
PdfGridRow row2 = grid.Rows.Add();
PdfGridRow row3 = grid.Rows.Add();
PdfGridRow row4 = grid.Rows.Add();
PdfGridRow row5 = grid.Rows.Add();
grid.Columns.Add(6);
//設置列寬
foreach (PdfGridColumn col in grid.Columns)
{
col.Width = 55f;
}
//寫入數據
row1.Cells[0].Value = "新入職員工基本信息";
row2.Cells[0].Value = "入職時間";
row2.Cells[1].Value = "姓名";
row2.Cells[2].Value = "部門";
row2.Cells[3].Value = "學歷";
row2.Cells[4].Value = "聯繫電話";
row2.Cells[5].Value = "正式員工";
row3.Cells[0].Value = "3月";
row3.Cells[1].Value = "馬超";
row3.Cells[2].Value = "研發部";
row3.Cells[3].Value = "碩士";
row3.Cells[4].Value = "153****6543";
row3.Cells[5].Value = "是";
row4.Cells[0].Value = "4月";
row4.Cells[1].Value = "劉陵";
row4.Cells[2].Value = "研發部";
row4.Cells[3].Value = "本科";
row4.Cells[4].Value = "176****5464";
row4.Cells[5].Value = "是";
row5.Cells[0].Value = "4月";
row5.Cells[1].Value = "張麗";
row5.Cells[2].Value = "研發部";
row5.Cells[3].Value = "本科";
row5.Cells[4].Value = "158****4103";
row5.Cells[5].Value = "是";
//水平和垂直方向合併單元格
row1.Cells[0].ColumnSpan = 6;
row4.Cells[0].RowSpan = 2;
row3.Cells[2].RowSpan = 3;
row4.Cells[3].RowSpan = 2;
//設置單元格內文字對齊方式
PdfTable table = new PdfTable();
row1.Cells[0].StringFormat = new PdfStringFormat(PdfTextAlignment.Center);
row4.Cells[0].StringFormat = new PdfStringFormat(PdfTextAlignment.Justify, PdfVerticalAlignment.Middle);
row3.Cells[2].StringFormat = new PdfStringFormat(PdfTextAlignment.Justify, PdfVerticalAlignment.Middle);
row4.Cells[3].StringFormat = new PdfStringFormat(PdfTextAlignment.Justify, PdfVerticalAlignment.Middle);
//設置單元格背景顏色
row1.Cells[0].Style.BackgroundBrush = PdfBrushes.LightGreen;
//設置表格邊框顏色、粗細
PdfBorders borders = new PdfBorders();
borders.All = new PdfPen(Color.Black, 0.1f);
foreach (PdfGridRow pgr in grid.Rows)
{
foreach (PdfGridCell pgc in pgr.Cells)
{
pgc.Style.Borders = borders;
}
}
//在指定位置繪入表格
grid.Draw(page, new PointF(0, 40));
//保存到文檔
doc.SaveToFile("PDF表格.pdf");
System.Diagnostics.Process.Start("PDF表格.pdf");
}
}
}
