将jcombobox添加到jtable单元格[重复]（2个答案）
20天前关门了。
我遇到的问题是，每次尝试将组合框添加到jtable文本时，都会弹出一个没有实际jcombobox的文本，而不是jcombobox中的文本

jTable1 = new javax.swing.JTable();
JComboBox comboBox = new JComboBox();
comboBox.addItem("baby");
comboBox.addItem("new");
comboBox.setEditable(true);
jTable1.setModel(new javax.swing.table.DefaultTableModel(
    new Object [][] {
        {"Opportunity Assessment", null, comboBox, null, null},
        {"IP Selection", null, null, null, null},
        {"Value Proposition Canvas Suite", null, null, null, null},
        {"Business Model Canvas", null, null, null, null},
        {"Market Opportunity Navigator", null, null, null, null},
        {"Porters 5 Forces-CSF", null, null, null, null},
        {"100 Customer Interviews", null, null, null, null},
        {"1000 Customer Surveys Complete", null, null, null, null},
        {"Minimum Viable Product", null, null, null, null},
        {"Competitive Advantage Chart", null, null, null, null},
        {"Go-to-Market Board", null, null, null, null},
        {"Financial Forecast-Link to Financials", null, null, null, null},
        {"Risk Analysis", null, null, null, null},
        {"Capital Needs-Link to Cap", null, null, null, null}
    },
    new String [] {
        "Tasks", "Status", "Results", "Insights", "Decision"
    }
));
jTable1.setEnabled(false);
jTable1.add(comboBox);
jScrollPane1.setViewportView(jTable1);
