To create a new table in Cloud Bigtable using the cbt command-line tool, you need to follow a series of steps. This answer will provide a detailed and comprehensive explanation of the process, ensuring a didactic value based on factual knowledge.

1. First, ensure that you have the necessary permissions to create a table in Cloud Bigtable. You should have the roles/bigtable.admin or roles/bigtable.user role assigned to your account.

2. Open the Cloud Shell in the Google Cloud Platform (GCP) Console. The Cloud Shell provides a command-line interface (CLI) with the necessary tools pre-installed.

3. Install the cbt command-line tool by running the following command in the Cloud Shell:

   gcloud components install cbt

This command will install the cbt tool, which is used to interact with Cloud Bigtable.

4. Authenticate with your GCP account by running the following command:

   gcloud auth login

This command will open a browser window where you can authenticate with your GCP credentials.

5. Once authenticated, set your project ID by running the following command:

   gcloud config set project PROJECT_ID

Replace PROJECT_ID with your actual GCP project ID.

6. Set the instance ID for Cloud Bigtable by running the following command:

   gcloud config set bigtable/instance_id INSTANCE_ID

Replace INSTANCE_ID with the ID of your Cloud Bigtable instance.

7. Now, you can create a new table in Cloud Bigtable using the cbt command. The syntax for creating a table is as follows:

   cbt createtable TABLE_ID

Replace TABLE_ID with the desired ID for your new table. The table ID must be unique within the Cloud Bigtable instance.

For example, to create a table named "mytable", you would run the following command:

   cbt createtable mytable

This command will create a new table named "mytable" in your Cloud Bigtable instance.

8. You can verify the creation of the table by listing all the tables in your Cloud Bigtable instance. Run the following command:

   cbt ls

This command will list all the tables in your Cloud Bigtable instance, including the newly created table.

Congratulations! You have successfully created a new table in Cloud Bigtable using the cbt command-line tool. You can now proceed to interact with the table by performing various operations such as writing data, reading data, and modifying the table schema.
