Tkinter网格布局异常：列宽与行高配置未生效问题求助

核心问题点 #

1. 混合使用布局管理器：主框架frame同时调用pack()和grid()，Tkinter不允许同一组件混用两种布局规则，直接导致布局逻辑冲突。
2. 第一行文本框拆分错误：需求是一个占5列的右侧文本框，但代码拆成两个组件（占2列+3列），增加布局复杂度且易引发列宽分配异常。
3. 图片固定宽度限制缩放：图片标签设置width=new_width强制固定宽度，忽略了列权重配置，导致对应列无法随窗口缩放。
4. 行权重设置不符合需求：第一行权重设为1会随窗口拉伸，但需求是行高适配图片最小高度，应设为0并指定最小高度。
5. 文本框固定高度：第一行文本框的height=7参数固定了高度，无法自适应图片高度。

关键修改说明 #

1. 移除混合布局调用：删除frame.grid()，仅保留frame.pack(expand=True, fill=tk.BOTH)，确保布局管理器唯一。
2. 合并第一行右侧文本框：将拆分的两个文本框合并为一个，设置columnspan=5，匹配需求的布局结构。
3. 取消图片固定宽度：删除image_label的width=new_width参数，让grid的sticky="nsew"和列权重控制图片宽度，实现随窗口缩放。
4. 调整行权重与最小高度：第一行设置weight=0和minsize=new_height，保证行高刚好适配图片；第二行设weight=1，占据窗口剩余垂直空间。
5. 移除文本框固定高度：删除第一行文本框的height=7参数，让高度随行高自适应图片尺寸。
