预览优先使用模板字体，未安装的字体使用本机同类字体替代。图片、图表、条件格式及部分特殊数字格式会提示在 Excel / WPS 中核对，不保证这些高级内容逐像素一致；模板导入窗口仍使用系统 Quick Look。 跨单元格文字占用空白单元格时，按实际字宽隐藏被跨过的竖边框；保留其他边框，不擅自加线或改变模板合并关系。支持堆叠竖排、底部对齐及会计格式的右侧金额填充，合并区域使用外围边框。这些规则按实际工作表、单元格和样式读取，不绑定内置模板的具体地址。优先使用本机模板字体，缺失字体采用系统替代并明确提示；图片、图表、条件格式等高级效果会提示在办公软件核对，不承诺任意模板与 WPS 逐像素相同。预览限制不改变导出的模板样式。
预览会刷新受支持公式的缓存（求和、同表引用、基本四则运算、条件判断、今日日期及内置人民币大写公式），保留公式本身。复杂自定义公式不猜测结果：移除旧缓存，明确列出尚未计算的单元格，由 Excel / WPS 打开后重算。预览属于屏幕表格展示，不是分页打印校样；打印设置保留在 Excel 中。 预览会刷新受支持公式的缓存（求和、同表引用、基本四则运算、条件判断、今日日期及内置人民币大写公式），保留公式本身。复杂自定义公式不猜测结果：移除旧缓存，明确列出尚未计算的单元格，由 Excel / WPS 打开后重算。预览属于屏幕表格展示，不是分页打印校样；打印设置保留在 Excel 中。
