推荐答案

您需要从TableColumnModel更新:

You need to update the TableColumn from the TableColumnModel:

TableColumnModel tcm = table.getColumnModel();
tcm.getColumn(0).setHeaderValue("whatever you want");

或者在创建JTable时可以覆盖getColumnName(...)方法:

Or you can override the getColumnName(...) method when you create your JTable:

JTable table = new JTable( DBUtilities.resultSetToTableModel(rs)
{
    private String[] columnNames = 
    {
        "Column 1",
        "Column 2",
        "Column ..."
    };

    @Override
    public String getColumnName(int col) 
    {
        return columnNames[col];
    }
};
