Word文档的正文和表格中都可以包含图片，我们已经介绍过如何提取正文中的图片，这篇文章将介绍如何提取表格中的图片。

原文档如下：

{
    class Program
    {
        static void Main(string[] args)

            //加载Word文档
            doc.LoadFromFile("sample.docx");

            //获取文档中第一个节
            Section section = doc.Sections[0];

            //调用ExtractImagesFromTables方法，提取表格中的图片
            ExtractImagesFromTables(section);

            //关闭
            doc.Close();
        }

        //创建静态方法ExtractImagesFromTables，参数为Section对象
        static void ExtractImagesFromTables(Section section)
        {
            int index = 0;

            //遍历section中的表格，提取表格中的图片并保存到本地
            foreach (Table table in section.Tables)
            {
                for (int i = 0; i < table.Rows.Count; i++)
