왼쪽 위 셀에서 첫 번째 열의 각 행으로 데이터 이동

Question

데이터를 표시하는 작은 응용 프로그램을 만들었습니다. 각 숫자는 공백으로 구분되지만 모든 숫자는 첫 번째 열의 각 행보다는 테이블의 왼쪽 위 열에 나타납니다. 누군가가 당신이 테이블에 데이터를 추가 할 수하지 않는 것

도와주세요 수 있습니다 - 나는 좋은 시간이 일하러 시도했지만 캔트 위해 분투.

그런 다음이 추가 시도 :

... 
    String[] numbers0 = Periodparagraphs.text().toString().split(" "); 
    String[] numbers = SSPparagraphs.text().toString().split(" ");//takes the ... 
    String[] numbers1 = SBPparagraphs.text().split(" "); 

    int tableRows; 

    if (numbers0.length > numbers.length && numbers0.length > numbers1.length) 
    { 
     tableRows = numbers0.length; 
    } 
    else if (numbers.length > numbers0.length && numbers.length > numbers1.length) 
    { 
     tableRows = numbers.length; 
    } 
    else 
    { 
     tableRows = numbers1.length; 
    } 
    //model = new DefaultTableModel(col, 90);//50 is number of rows --You don't seem to need this 

    Object[][] data = new Object[tableRows][3]; 

    for (int x = 0; x < tableRows; x++) 
    { 
     try 
     { 
      data[x][0] = numbers1[x]; 
     } 
     catch (IndexOutOfBoundsException e) 
     { 
      data[x][0] = "-"; 
     } 

     try 
     { 
      data[x][1] = numbers[x]; 
     } 
     catch (IndexOutOfBoundsException e) 
     { 
      data[x][1] = "-"; 
     } 

     try 
     { 
      data[x][2] = numbers0[x]; 
     } 
     catch (IndexOutOfBoundsException e) 
     { 
      data[x][2] = "-"; 
     } 
    } 



    table = new JTable(data,col) 
    { 
     @Override 

     public boolean isCellEditable(int arg0, int arg1) 
     { 
      return false; 
     } 
    }; 

는 또한, 내가 제대로 표시 할 프로젝트를 얻을 수 없습니다 (전혀, 정말). Flow Layout (나는 Spring을 선호한다) 이외에 다른 레이아웃 옵션을 탐구하고 싶을지도 모른다. 또, JScrollPane가 도움이됩니다.
