                        Name
                        Sport
                        City
                        Featured
                    
                
                
                    
                        {{team.name}}
                        {{team.sport}}
                        {{team.city}}
                        {{team.featured}}

Name	Sport	City	Featured
{{team.name}}	{{team.sport}}	{{team.city}}	{{team.featured}}

问一下上面下拉框选择之后筛选有问题，但不知道是哪里出问题了？

我给你改好了一个，你对照的看看吧。我感觉如果加上value以后就不会有现在这个问题了。
