# Display Output In A Vertical Format
Output for tables with lots of columns can be hard to read and sometimes
overflow the terminal window. Consider the output from [Show Indexes For A
Table](show-indexes-for-a-table.md):
```sql
> show indexes in users;
+-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
| Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | Index_comment |
+-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
| users | 0 | PRIMARY | 1 | id | A | 0 | NULL | NULL | | BTREE | | |
| users | 0 | unique_email | 1 | email | A | 0 | NULL | NULL | | BTREE | | |
+-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
```
We can vertically orient the output of a statement by terminating it with
`\G` instead of `;` (or `\g`).
```sql
> show indexes in users\G
