Extjs gridpanel 合并单元格

  1 /*
  2          * *合并单元格的函数，合并表格内所有连续的具有相同值的单元格。调用方法示例：
  3          * *store.on("load",function(){gridSpan(grid,"row","[FbillNumber],[FbillDate],[FAudit],[FAuditDate],[FSure],[FSureDate]","FbillNumber");});
  4          * *参数：grid-需要合并的表格,rowOrCol-合并行还是列,cols-需要合并的列（行合并的时候有效）,sepCols以哪个列为分割(即此字段不合并的2行，其他字段也不许合并)，默认为空
