生成带有表格的word附件和动态赋值，
表格前后需要添加一个特殊的开始和结束的域，表格第一列 TableStart:AuditJdcttbzInfo 和表格的最后一列 TableEnd:AuditJdcttbzInfo，然后再添加这个第一列和最后一列的需要展示的值得域；
点击打印（生成）附件按钮，执行得后台代码：
List<Integer> selectedlist = tableModel.getSelectedIndexes(); String jdcttbzRowguidStr = ""; if (selectedlist != null && selectedlist.size() > 0) { int i = 1; for (Integer index : selectedlist) { Object[] arrobj = tableModel.getRowData().get(index); jdcttbzRowguidStr += arrobj[0]; if(i<selectedlist.size()){ jdcttbzRowguidStr += ","; } i++; } } System.out.println("=======重定向地址==="+JsfHelper.getRequestCompleteUrl()+"/xxx/windowbusiness/businessmanage/PrintJdcttbzShbAndHzb.html?strs="+jdcttbzRowguidStr); sendRedirect(JsfHelper.getRequestCompleteUrl()+"/xxx/windowbusiness/businessmanage/PrintJdcttbzShbAndHzb.html?strs="+jdcttbzRowguidStr);
其中tableModel是展示在页面的一个table样式得表格数据简单封装，作用是可以获取到所选的多行数据，讲这些选择的多行数据的每一行的唯一标识，拼接成一个用一个特殊符号隔开的字符串，需要放在重定向的地址后面传参给方法；
重定向后的生成打印附件的页面的后台方法：

其中DocAttachFile为附件存储的表对应的实体类，docAttachFileService为其业务逻辑实施层；
