jQuery.extend($.fn.fmatter , {
    customIsOpen : function(cellvalue, options, rowobject) {
        if(cellvalue == 1)
return "开放";
else
return "没有开放";
    }
});
jQuery.extend($.fn.fmatter.customIsOpen , {
unformat : function(cellvalue, options, cellobject) {
var value = $(cellobject).html() == "开放" ? "1" : "0";
return value;
}
});
