### Search before asking
- [X] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues.
### Describe the bug
Current zorder implementation does not support columns with special characters.
If we try to create a table with special characters in column names and then optimize it with zorder, it will throw an error.
```sql
CREATE TABLE up (c1 INT, `@c2` INT, c3 INT);
OPTIMIZE up ZORDER BY c1, `@c2`;
```
```
Column '```@c2```' does not exist. Did you mean one of the following? [spark_catalog.default.up.c1, spark_catalog.default.up.c3, spark_catalog.default.up.@c2]; line 1 pos 0;
'OptimizeZorderStatement [up]
+- 'Sort [zorder(c1#15, '`@c2`) ASC NULLS LAST], true
+- Project [c1#15, @c2#16, c3#17]
+- SubqueryAlias spark_catalog.default.up
+- HiveTableRelation [`default`.`up`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [c1#15, @c2#16, c3#17], Partition Cols: []]
org.apache.spark.sql.AnalysisException: Column '```@c2```' does not exist. Did you mean one of the following? [spark_catalog.default.up.c1, spark_catalog.default.up.c3, spark_catalog.default.up.@c2]; line 1 pos 0;
