Npoi導出word(Peanuts)

          一個項目，要做一個從數據庫讀取數據，然後導出到word，因爲涉及到後臺數據庫的讀取，決定用npoi來導出word。

         NPOI源碼地址：http://npoi.codeplex.com/

        NPOI 2.0 api文檔： http://www.npoi.info/npoi2tutorial

       因爲npoi操作word的文章比較少，在由於版本不同，相關的函數可能不一樣，這個就需要大家自己去慢慢的探索了。

      例如：作者的api文檔中

c.字體加粗

r1.SetBold(true);

實際我在調用時，調用的接口是 r1c1.IsBold = 12;

我使用的版本是：NPOI v2.2.0.0

需要引用的命名空間如下

using NPOI.XWPF.UserModel;
using NPOI.OpenXmlFormats.Wordprocessing;

        

        最終效果圖如下：

     

     關鍵代碼如下：

        //創建run對象
        //本節提到的所有樣式都是基於XWPFRun的，
        //你可以把XWPFRun理解成一小段文字的描述對象，
        //這也是Word文檔的特徵，即文本描述性文檔。

設置table的寬度，以及沒列的寬度代碼如下：

        tableTop.Width = 1000 * 5;/* 設置table寬度，必須設置width，SetColumnWidth纔有效 */
        tableTop.SetColumnWidth(0, 1300);/* 設置第一列寬 */
        tableTop.SetColumnWidth(1, 500);/* 設置第二列寬 */
        tableTop.SetColumnWidth(2, 1000);/* 設置列寬 */
        tableTop.SetColumnWidth(3, 500);/* 設置列寬 */
        tableTop.SetColumnWidth(4, 1700);/* 設置列寬 */

和並列以及設置列的高度：

 tableTop.GetRow(0).MergeCells(1, 4);/* 合併列 */

XWPFRun r1c1 = pCell.CreateRun();
        r1c1.SetText(setText);
        r1c1.FontSize = 12;
        r1c1.SetFontFamily("華文楷體", FontCharRange.None);//設置雅黑字體
        r1c1.SetTextPosition(textPos);//設置高度
