-- 1. 为维修单主表添加富文本内容字段（维修描述）
ALTER TABLE `dm_repair_order` 
ADD COLUMN `rich_text_content` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL COMMENT '富文本内容（维修描述）' AFTER `remark`;

-- 2. 为维修单明细表添加富文本内容字段（放在fault_name后面）
ALTER TABLE `dm_repair_order_entry` 
ADD COLUMN `rich_text_content` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL COMMENT '富文本内容' AFTER `fault_name`;
