最近项目中一直在写XML、Table、Excel之间的转化。之前一直都是不考虑格式的导出，今天给出一个格式，让按照格式导出，还真把我这新手为难了一翻，网上给出的资料基本一样。为了一个单元格文字变色纠结了很久。下面把学习资料发出，希望对新手学习有所帮助：
下面是会用到的导出属性。
合并单元格属性：
[csharp] view
plain copy
worksheet.get_Range(worksheet.Cells[rowIndex, columnCount + 1], worksheet.Cells[rowIndex + 2, columnCount + 1]).MergeCells = true;
设置某一个单元格中字体的颜色：
[csharp] view
plain copy
worksheet.get_Range(worksheet.Cells[rowIndex, 5], worksheet.Cells[rowIndex, 8]).Font.ColorIndex = 5;//这个在网上找的一直变不了色，后面自己试出来了
字体颜色的index值：
选定区间设置字符串格式或数字格式：
[csharp] view
plain cop
24ade
y
Microsoft.Office.Interop.Excel.Range range = worksheet.get_Range(worksheet.Cells[rowIndex, 1], worksheet.Cells[rowCount+rowIndex-1, columnCount-1]);
range.NumberFormat = "@";//设置数字文本格式
Microsoft.Office.Interop.Excel.Range rangeinfo = worksheet.get_Range(worksheet.Cells[rowIndex, 4], worksheet.Cells[rowCount + rowIndex - 1, 4]);
rangeinfo.NumberFormat = "00";
用于汇总和计算时(所计算的字段值必须是数字格式)：
[csharp] view
plain copy
worksheet.Cells[rowIndex + i, columnCount+1] = "=CEILING(D" + (rowIndex + i).ToString() + "*1.01+1,2)"; //i是变量
-------------------------------------------------------------------
PS：以下代码则可导出如下图的Excel格式：
[csharp] view
plain copy
/// 导出为Excel格式文件
/// </summary>
/// <param name="dt">作为数据源的DataTable</param>
/// <param name="saveFile">带路径的保存文件名</param>

rowIndex++;
//第二行内容
