我正在试图解决这个问题并搜索了很多内容。但我找不到任何东西。
这是我第一次在StackOverflow上提问。
如果我无法正确解释我的问题，请耐心等待。
任何帮助都会受到赞赏。

您正在使用多次添加相同的对象。即你正在向窗格中添加相同的“名称”变量，在Javafx中是一个很大的没有，更好的方法是
ArrayList<Text> myText = new ArrayList<Text>();
try
{
FileReader fr = new FileReader("score.txt");
br = new BufferedReader(fr);
String line;
while((line = br.readLine()) != null)
{
//Splitting words so that I can print out ID, Name and Score
//If i don't use split it just prints out score...because score gets written at last in file
String[] words = line.split(",");
for(int i =0; i<words.length; i++)
{
Text temp = new Text();
temp.setText(words[i]);
temp.setStyle(TEXT_STYLE);
temp.setFill(Color.WHITE);
myText.add(temp) //allows you to edit these later
/*
* HERE IS THE PROBLEM
* Every time it reads line from text file
* I add it to gridPane below Header
* but i want to add rows dynamically but i get illegalArgumentException
*/
gridPane.add(temp,2,i+1);
}
}
br.close();
}
