Java 假设玩家信息是表中的另一列（或多列）。也许你可以上传一个截图，告诉我你到底想做什么。我现在在打电话，但我可以稍后上传一个截图。该表基本上是球员姓名、Id、位置、出生国和球队。真的没有别的了。id是主键并自动生成。顺便说一句，这是图像，感谢您之前的帮助。它打

假设玩家信息是表中的另一列（或多列）。也许你可以上传一个截图，告诉我你到底想做什么。我现在在打电话，但我可以稍后上传一个截图。该表基本上是球员姓名、Id、位置、出生国和球队。真的没有别的了。id是主键并自动生成。顺便说一句，这是图像，感谢您之前的帮助。它打印得很完美，但现在我当然在第二个循环中挣扎。。。我试着按照你的编辑，但是不行！。用于img的Thx。你必须是一个特殊的人。什么不起作用？到目前为止，你试图解决什么问题？如有必要，也请添加一些代码和输出
