Step1 提取不同Sheet中特定维度（如“B1层”）的数值，并进行跨表逻辑对比。

# 定义提取逻辑：定位目标行（如包含'B1'的行）并获取其关联的系数
def extract_target_value(df, target_label='B1', label_col_idx=0, offset_row=1, value_col_idx=2):
    """
    在指定列搜索标签，并返回其相对偏移位置的数值
    """
    extracted_values = []
    for idx, row in df.iterrows():
        if str(row.iloc[label_col_idx]).strip() == target_label:
            # 提取目标行下方或特定偏移位置的数值
            if idx + offset_row < len(df):
                val = df.iloc[idx + offset_row].iloc[value_col_idx]
                extracted_values.append(val)
    return extracted_values

# 分别读取需要对比的Sheet
sheet1_df = pd.read_excel(file_path, sheet_name='Sheet1')
sheet2_df = pd.read_excel(file_path, sheet_name='Sheet2')

# 提取系数（示例：B1层的换算系数）
# 注意：不同Sheet的列索引可能不同，需根据实际结构调整
s1_coeffs = extract_target_value(sheet1_df, target_label='B1', label_col_idx=1, value_col_idx=3)
s2_coeffs = extract_target_value(sheet2_df, target_label='B1', label_col_idx=0, value_col_idx=2)

# 汇总对比数据
