用拼xml方式导出excel
xml对应的excel格式可以自己在建立一个Excel，另存为xml格式，可以看到表格合并，类型等等的拼xml方法
变颜色拼法
sw.WriteLine(" <ExcelWorkbook xmlns=\"urn:schemas-microsoft-com:office:excel\">");
sw.WriteLine(" <WindowHeight>8955</WindowHeight>");
sw.WriteLine(" <WindowWidth>11355</WindowWidth>");
sw.WriteLine(" <WindowTopX>480</WindowTopX>");
sw.WriteLine(" <WindowTopY>15</WindowTopY>");
sw.WriteLine(" <ProtectStructure>False</ProtectStructure>");
sw.WriteLine(" <ProtectWindows>False</ProtectWindows>");
sw.WriteLine(" </ExcelWorkbook>");
sw.WriteLine(" <Styles>");
sw.WriteLine(" <Style ss:ID=\"Default\" ss:Name=\"Normal\">");
sw.WriteLine(" <Alignment ss:Vertical=\"Center\"/>");
sw.WriteLine(" <Borders/>");
sw.WriteLine(" <Font ss:FontName=\"宋体\" x:CharSet=\"134\" ss:Size=\"12\"/>");
sw.WriteLine(" <Interior/>");
sw.WriteLine(" <NumberFormat/>");
sw.WriteLine(" <Protection/>");
sw.WriteLine(" </Style>");
sw.WriteLine("<Style ss:ID='s28'><Font ss:FontName='宋体' x:CharSet='134' ss:Size='12' ss:Color='#FF0000'/></Style>");
sw.WriteLine(" </Styles>");
//需要什么字体去引用id就行了例如上边的ss:ID='s28',拼样式的时候貌似都要加个ss:ID=\"Default\"，让没有直接指定id的使用默认的样式
需要导出的excel与数据源的颜色一致只需把需要变颜色的坐标记录下来就行了
例如此时diccor 是key是行列的坐标,value就是需要变成的颜色的id,导出时需要得到每个格子的值，当然也能得到坐标,就可以变成相应的颜色了
Dictionary<string,string> diccor = new Dictionary<string,string>();
foreach (var item in dic)
{
diccor[item.Key + "" + item.Value] = "ss:StyleID='s28'";
