Python3.10将多个word文件合并，合并之后的文档不要改变原本文档中的任何格式，包括字体颜色啥的，要求代码可以打包为exe，双击之后弹出页面，页面首先选择输入文件夹，再选择输出文件夹，再输入合并以后的名字，最后点击开始，显示进度条，颜色为蓝色，进度条中要有百分比，给出代码，使用pyqt5界面化，界面要整洁干净，看着舒服，要注意，我之前的相关代码，运行之后会弹出Python停止工作的提示，请避免

以下是实现上述功能的Python代码，使用PyQt5实现界面化：

from PyQt5.QtCore import Qt, QThread, pyqtSignal
from PyQt5.QtGui import QPalette, QColor, QBrush, QPixmap

        self.files_list = files_list
        self.output_path = output_path
        self.output_name = output_name

    def run(self):
        total_files = len(self.files_list)
        merged_doc = Document(self.files_list[0])
        self.update_progress(1, total_files)
        for i in range(1, total_files):
            doc = Document(self.files_list[i])
            for p in doc.paragraphs:
                merged_doc.add_paragraph(p.text, p.style)
            for t in doc.tables:
                merged_table = merged_doc.add_table(
                    rows=t.rows.count(), cols=t.columns.count())
                for r in range(len(t.rows)):
                    for c in range(len(t.columns)):
                        merged_table.cell(r, c).text = t.cell(r, c).text
                        merged_table.cell(r, c).width = t.cell(r, c).width
            self.update_progress(i + 1, total_files)
        merged_doc.save(os.path.join(self.output_path, self.output_name))

        progress_percent = int(current / total * 100)
        self.progress_signal.emit(progress_percent)

注意事项：

1. 程序需要一个名为 `background.jpg` 的背景图片，放在代码文件同级目录下。
2. 程序还需要 `docx` 模块的支持，可以使用 `pip install python-docx` 命令进行安装。
3. 程序使用了多线程来实现进度条功能，因此需要在合并过程中更新进度条，避免界面卡死。
