REVISIONS:
Ver Date Author Description

---

1.0 2011/2/19 Anton Scheffer 1,New Create the pkg
1.1 2015/6/10 Sam.T 1.优化核心处理生成xlsx的代码，使得生成文档的执行效率大大提高！
1.1 2015/6/10 Sam.T 1.query2sheet增加绑定变量的可选输入参数。
1.2 2015/6/15 Sam.T 1.代码增加调试模式。直接设置G_DEBUG_MODE变量即可。
1.2 2015/6/20 Sam.T 1.为方便使用，再次封装一些简单易用的过程，生成xlsx文档
1.2 2015/7/5 Sam.T 1.单条sql生成xlsx文档的内容，增加是否显示foot，以及显示的行数。
jinzhao 解决数据量较大情况下导出excel报错xml的问题。将dbms_lob.writeappend修改为dbms_lob.append

  使用方法：

  sql;"> declare l_sql varchar2(30000); begin l_sql := 'select * from all_objects'; smt_xlsx_maker_pkg.query2sheet(l_sql,'Export2.xlsx'); end;

  除此之外，基本上Excel 中有的效果它都可以生成。

  以下一个例子，包括居中，合并单元格，底色，新增工作表等：
  

  sql;"> begin

smt_xlsx_maker_pkg.clear_workbook;
smt_xlsx_maker_pkg.new_sheet;
smt_xlsx_maker_pkg.cell(5,'Export3.xlsx');
end;
