List columns in table from console

To list columns in a table from the console in Ruby, you can follow these steps:

1. Open the console or terminal.
2. Access the Ruby environment by typing "irb" and pressing Enter.
3. Connect to the database using the appropriate connection settings.
4. Once connected, execute the command to list the columns in the table. This can be achieved by typing the following command: "ModelName.column_names", where "ModelName" is the name of the model representing the table.

Executing these steps will display the columns of the table, providing insight into its structure.
