+
+本 skill 对应 shortcut：`lark-cli sheets +batch-set-style`。
+
+对多个范围批量设置不同的单元格样式，一次请求可包含多组范围和样式。
+
+> [!CAUTION]
+> 这是**写入操作** —— 执行前必须确认用户意图。可以先用 `--dry-run` 预览。
+
+## 命令
+
+```bash
+# 对两组范围分别设置样式
+lark-cli sheets +batch-set-style --spreadsheet-token "shtxxxxxxxx" \
+  --data '[{"ranges":["<sheetId>!A1:C3"],"style":{"font":{"bold":true},"backColor":"#21d11f"}},{"ranges":["<sheetId>!D1:F3"],"style":{"foreColor":"#ff0000"}}]'
+
+# 同一样式应用到多个范围
+lark-cli sheets +batch-set-style --spreadsheet-token "shtxxxxxxxx" \
+  --data '[{"ranges":["<sheetId>!A1:B2","<sheetId>!D4:E5"],"style":{"hAlign":1,"font":{"bold":true}}}]'
+
+# 仅预览
+lark-cli sheets +batch-set-style --spreadsheet-token "shtxxxxxxxx" \
+  --data '[{"ranges":["<sheetId>!A1:B2"],"style":{"backColor":"#0000ff"}}]' --dry-run
+```
+
+## 参数
+
+| 参数 | 必填 | 说明 |
+|------|------|------|
+| `--url <url>` | 否 | 电子表格 URL（与 `--spreadsheet-token` 二选一） |
+| `--spreadsheet-token <token>` | 否 | 表格 token（与 `--url` 二选一） |
+| `--data <json>` | 是 | JSON 数组，每项包含 `ranges`（字符串数组）和 `style`（样式对象） |
+| `--dry-run` | 否 | 仅打印参数，不执行请求 |
+
+### style 对象字段
+
+与 `+set-style` 相同，参见 [lark-sheets-set-style](lark-sheets-set-style.md)。
+
+## 输出
+
+JSON，包含：
+
+- `totalUpdatedRows/totalUpdatedColumns/totalUpdatedCells`：汇总更新量
+- `revision`：工作表版本号
+- `responses[]`：每个范围的更新详情
