notebook 设置每个table的宽度

用notebook来做菜单时，每个table的大小未必是相等的，所以希望可以根据实际情况设置每个table的大小，是否可以将struct rtgui_notebook下的 tab_w, tab_h移到struct rtgui_notebook_tab下，这样就可以随便设置每个table的大小？
```struct rtgui_notebook
{
    struct rtgui_widget parent;

rt_uint8_t flag;

/* widget private data */
    struct rtgui_notebook_tab *childs;
    rt_uint16_t count;
    rt_int16_t current;

rt_uint16_t tab_w, tab_h;
};
struct rtgui_notebook_tab
{
#ifdef RTGUI_USING_NOTEBOOK_IMAGE
    struct rtgui_image *pressed_image;
    struct rtgui_image *unpressed_image;
#endif

struct rtgui_widget *widget;
    char *title;
};```

我想把这个控件给重构下，但是有点地方没有看懂，_rtgui_notebook_draw_bar函数里rtgui_dc_fill_rect(dc, &rect);填充一个矩形是填充的什么？我感觉后面for循环才是绘制的table，这里填充貌似多余了。
```static void _rtgui_notebook_draw_bar(struct rtgui_notebook *notebook,
                                     struct rtgui_dc *dc)
{
    int index;
    struct rtgui_rect rect;
    struct rtgui_rect text_rect;
#ifdef RTGUI_USING_NOTEBOOK_IMAGE
    struct rtgui_image *image = RT_NULL;
    struct rtgui_rect image_rect;
#endif

RT_ASSERT((notebook != RT_NULL) && (dc != RT_NULL));

if (notebook->flag == RTGUI_NOTEBOOK_NOTAB)
        return;

_rtgui_notebook_get_bar_rect(notebook, &rect);
    rtgui_dc_fill_rect(dc, &rect);```
