+ * 2) Service 侧将明细数据转换为 {@code List<RowRenderData>}，并放入 data：{@code data.put("detailsTable", rows)}。
+ * 3) Controller 侧使用 {@code Configure.builder().bind("detailsTable", new WmsShippingDetailTablePolicy()).build()} 绑定策略，
+ *    再调用 {@code WordTemplateUtil.renderToResponse(..., config, response)} 输出。
+ * <p>
+ * 注意事项：
+ * - 本策略会删除模板行并插入新行，因此模板行不建议做复杂单元格合并，否则插入行结构可能与预期不一致。
+ * - 当 rows 为空或为 null 时：会删除模板行并保留表头（避免用户看到占位符）。
+ * <p>
+ * 常见问题：
+ * - 表格不渲染/仍显示 {{detailsTable}}：检查占位符名称与 bind key、data key 是否一致；并确认使用了带 Configure 的导出方法。
+ * - ClassCastException：传入的 data 必须是 {@code List<RowRenderData>}，不要传 {@code List<Map<String,Object>>}。
