Java JTable设置列宽实现表格不等宽

在Java程序设计中，会经常用到JTable组件，默认的JTable组件的列宽是等长的,

如此这般就限制了表格的美观性。如果有一列是实现身份证号码的，这一列宽度

就会明显的不足，所以我们要解决这种情况，代码如下所示:

public void TableTest() {
        String[] type = {"列1","列2","列3","列4","列5","列6","列7"};
        Vector<String> Column = buildTableModel(type);
        Vector<Vector<String>> Values = new Vector<Vector<String>>();
        DefaultTableModel Model = new DefaultTableModel(Values, Column);
        JTable tab = buildTable(Model);
        tab.setColumnModel(getColumn(table, width));    //设置不等列宽，width是int型一维数组
    }
    /**

    public Vector<String> buildTableModel(String[] type) {
        Vector<String> vector = new Vector<String>();
        for (int i = 0; i < type.length; i++)
            vector.add(type[i]);
        return vector;
    }
    /**

     */
    public static JTable buildTable(DefaultTableModel model) {
        JTable table = new JTable(model);
        table.setShowGrid(true);
        table.setGridColor(Color.BLUE);
        table.setRowHeight(20);
        table.setFont(new Font("", Font.PLAIN, 12));
        return table;
    }
    /**

    public static TableColumnModel getColumn(JTable table, int[] width) {
        TableColumnModel columns = table.getColumnModel();
        for (int i = 0; i < width.length; i++) {
            TableColumn column = columns.getColumn(i);
            column.setPreferredWidth(width[i]);
        }
        return columns;
    }
