在我的数据库中，我在一列中有两个选项：
- /上传/1369839038.zip
- 无效的
现在我已经格式化了“电子邮件”列，所以它显示为一个链接，
formatter:function(cellvalue, options, rowObject){
return '<a href="' + cellvalue + '"target="_blank">FILES </a> '
} }
但是我想制作一个格式化程序，如果它具有“NULL”，则显示为空白，如JQGRID 显示空白而不是 Null或显示为我已经拥有的链接。我想为这个“附件”列将两者结合在一个格式化程序中，以便它根据数据显示，无论是链接还是空白。请一些帮助，非常感谢。
