OpenXml操作word模板并导出

  在工作中,由于会需要对word模板进行数据填充,并导出为新文件,便对word相关的类库做了简单的了解。

  1.NPOI

          NPOI对excel的支持相当给力,但是对于word的支持却明显不到位,我在使用时导出新文件始终报错无法打开。

  2.Spire 

    功能强大,专业,支持全面。商业化软件,需要收费,有免费版不过有限制(会在文档里加上版权文字,可以删掉。。。)

  3.OpenXml

    较为底层的操作OpenXml文档的类库,提供了对word的支持,功能全面,速度快。

    对word文档的操作,在我的需求里 主要是填充word表格的数据 和替换段落的标签数据。下面附代码

    需要使用到DocumentFormat.OpenXml类库,nuget:install-package DocumentFormat.OpemXml

        public void SetTableData(int tableIndex, DataTable datatable, IList<WordTableColumnConfig> configs, int headSpan = 1)
        {
            if (doc == null)
                throw new Exception("word parse failed.");
            if (tableIndex < 0 || tableIndex > Tables.Count - 1)
                throw new Exception("tableIndex is out of range.");
            if (datatable == null)
