本文介绍如何利用OWC创建Excel文件，包括设置标题、表格样式及数据填充，并通过ActiveX在网页上展示生成的报表。
主要利用OWC生成Excel,画表头和显示从数据库读出来的数据,然后显示在前台页面上,无需客户端安装office,只需要安装owc.
后面利用OWC操作EXCEL,并且生成文件的操作
SpreadsheetClass xlsheet = new SpreadsheetClass();
设置标题#region 设置标题
//写标题 //合并单元格 xlsheet.get_Range(xlsheet.Cells[1, 1], xlsheet.Cells[1,30]).set_MergeCells(true); xlsheet.ActiveSheet.Cells[1, 1] = "采购执行情况一览表"; //字体加粗 xlsheet.get_Range(xlsheet.Cells[1, 1], xlsheet.Cells[1, 30]).Font.set_Bold(true); //单元格文本水平居中对齐 xlsheet.get_Range(xlsheet.Cells[1, 1], xlsheet.Cells[1, 30]).set_HorizontalAlignment(XlHAlign.xlHAlignCenter); //设置字体大小 xlsheet.get_Range(xlsheet.Cells[1, 1], xlsheet.Cells[1,30]).Font.set_Size(14);

这样其实有一个问题,要控制生成的报表在不同的文件夹下面,否则会不同的人调用相同的报表.由于在最后并没有采用这种方案,所以也没有时间考虑这些了
前台用Activex显示Excel
