Npoi导出word(Peanuts)

          一个项目，要做一个从数据库读取数据，然后导出到word，因为涉及到后台数据库的读取，决定用npoi来导出word。

         NPOI源码地址：http://npoi.codeplex.com/

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

       因为npoi操作word的文章比较少，在由于版本不同，相关的函数可能不一样，这个就需要大家自己去慢慢的探索了。

      例如：作者的api文档中

c.字体加粗

r1.SetBold(true);

实际我在调用时，调用的接口是 r1c1.IsBold = 12;

我使用的版本是：NPOI v2.2.0.0

需要引用的命名空间如下

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

        

        最终效果图如下：

     

     关键代码如下：

     

  /// <summary>
    /// 新增
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnPrint_Click(object sender, EventArgs e)
    {
        //创建document对象
        XWPFDocument doc = new XWPFDocument();
        //创建段落对象
        XWPFParagraph p1 = doc.CreateParagraph();
        p1.Alignment = ParagraphAlignment.CENTER;//字体居中
        //创建run对象
        //本节提到的所有样式都是基于XWPFRun的，
        //你可以把XWPFRun理解成一小段文字的描述对象，
        //这也是Word文档的特征，即文本描述性文档。

设置table的宽度，以及没列的宽度代码如下：

        tableTop.Width = 1000 * 5;/* 设置table宽度，必须设置width，SetColumnWidth才有效 */
        tableTop.SetColumnWidth(0, 1300);/* 设置第一列宽 */
        tableTop.SetColumnWidth(1, 500);/* 设置第二列宽 */
        tableTop.SetColumnWidth(2, 1000);/* 设置列宽 */
        tableTop.SetColumnWidth(3, 500);/* 设置列宽 */
        tableTop.SetColumnWidth(4, 1700);/* 设置列宽 */

和并列以及设置列的高度：

 tableTop.GetRow(0).MergeCells(1, 4);/* 合并列 */

XWPFRun r1c1 = pCell.CreateRun();
        r1c1.SetText(setText);
        r1c1.FontSize = 12;
        r1c1.SetFontFamily("华文楷体", FontCharRange.None);//设置雅黑字体
        r1c1.SetTextPosition(textPos);//设置高度
