私が間違っていることは得られません。すべてがOKだと思われますが、データはテーブルにロードされません。 これは、ステージのコントローラクラスである：JavaFXなぜTableViewにデータがロードされないのですか

// Constructors
public MeetingData(String date, String place, String category, String contacts, String comments) {

this.place = place;
this.category = category;
this.contacts = contacts;

}
// Setters
public void setDate(String date) {
this.date = date;
}
public void setPlace(String place) {
this.place = place;
}
public void setCategory(String category) {
this.category = category;
}
public void setContacts(String contacts) {
this.contacts = contacts;
}
public void setComments(String comments) {
this.comments = comments;
}
// Getters
public String getDate() {
return date;
}
public String getPlace() {
return place;
}
public String getCategory() {
return category;
}
public String getContacts() {
return contacts;
}
public String getComments() {

あなたは私を助けることができる場合、私は非常に感謝されると間違いがどこから来たのか説明してください。
のですか？ – Phil
ObservableListのコンソールから何かを印刷しようとしましたが、テーブルにロードできません。 MeetingDataクラスのStringをSimpleStringPropertyに変更し、defaulコンストラクタを作成し、getterとsetterを変更して、何も起こっていません。テーブルの中に "No content in table"と書いてあります。 – Phil
私はもう一度変更を試みました – Phil
