Java GUI表中只有一列获得输入

Question

我正在创建一个表格，我想用4个列中的组合框输入每个单元格，这是我的代码：

protected void createContents() {
    shell = new Shell();    

    table = new Table(shell, SWT.BORDER | SWT.FULL_SELECTION);      

    TableColumn tblclmnCallers = new TableColumn(table, SWT.NONE);
    tblclmnCallers.setWidth(100);
    tblclmnCallers.setText("Callers");


    TableColumn tblclmnCallersExecuted = new TableColumn(table, SWT.NONE);
    tblclmnCallersExecuted.setWidth(150);
    tblclmnCallersExecuted.setText("CallersExecuted");

    TableColumn tblclmnCallees = new TableColumn(table, SWT.NONE);
    tblclmnCallees.setWidth(100);
    tblclmnCallees.setText("Callees");

    TableColumn tblclmnCalleesExecuted = new TableColumn(table, SWT.NONE);
    tblclmnCalleesExecuted.setWidth(150);
    tblclmnCalleesExecuted.setText("CalleesExecuted");

    int i = 0;
    for (MethodTrace2 meth : methodtraces2) {
        TableItem item1 = new TableItem(table, SWT.NONE);


        List<Method2Representation> callees = meth.getCalleesList();
        List<Method2Representation> callers = meth.getCallersList();
        List<Method2Representation> callersExecuted = meth.getCallersListExecuted();
        List<Method2Representation> calleesExecuted = meth.getCalleesListExecuted();



        TableEditor tableEditor = new TableEditor(table);

        if (i < 100) {
            TableItem[] items = table.getItems();

            items = table.getItems();
            CCombo comboCallers = new CCombo(table, SWT.NONE);
            comboCallers.setText("Callers");
            for (Method2Representation caller : methodtraces2.get(i).getCallersList()) {
                comboCallers.add(caller.toString());

            }

            // items = table.getItems();
            CCombo comboCallees = new CCombo(table, SWT.NONE);
            comboCallees.setText("Callees");
            for (Method2Representation callee : methodtraces2.get(i).getCalleesList()) {
                comboCallees.add(callee.toString());

            }

            items = table.getItems();
            CCombo comboCallersExecuted = new CCombo(table, SWT.NONE);
            comboCallersExecuted.setText("CallersExecuted");
            for (Method2Representation callerExecuted : methodtraces2.get(i).getCallersListExecuted()) {
                comboCallersExecuted.add(callerExecuted.toString());

            }
            items = table.getItems();
            CCombo comboCalleesExecuted = new CCombo(table, SWT.NONE);
            comboCalleesExecuted.setText("CalleesExecuted");
            for (Method2Representation calleeExecuted : methodtraces2.get(i).getCalleesListExecuted()) {
                comboCalleesExecuted.add(calleeExecuted.toString());

            }
            tableEditor.setEditor(comboCallers, item1, 10);
            tableEditor.setEditor(comboCallees, item1, 11);
            tableEditor.setEditor(comboCallersExecuted, item1, 12);
            tableEditor.setEditor(comboCalleesExecuted, item1, 13);

            tableEditor.grabHorizontal = true;
            i++;
        }

    }



}

只有第13列“CalleesExecuted”获得带有相应组合框的输入，第10,11和12列完全留空，即使我也编写了用于输入它们的代码，我不知道什么是错的以及它们为什么不输入< / p>
