You may create a new column by clicking the "Create new column" link at the top of the page.

The list of columns displays the following information:

Property	Description
Key	Indicates that the column is the primary key in the table
ID	Indicates that the column is an auto-incrementing identifier
Name	The name of the column
Data Type	The data type for the column
Size	The size (in bytes) of the column
Nulls	Indicates that the column allows null values
Default	The default value for the column

You can also edit or delete a column from this page by clicking the appropriate links. Note that columns are only editable if the table itself contains no data. That is, you can redesign an existing table only if it is empty.
