     * ### Attributes
     *
     * Columns can have several attributes:
     *
     * - `type` The type of the column. This should be
     *   one of CakePHP's abstract types.
     * - `length` The length of the column.
     * - `precision` The number of decimal places to store
     *   for float and decimal types.
     * - `default` The default value of the column.
     * - `null` Whether the column can hold nulls.
     * - `fixed` Whether the column is a fixed length column.
     *   This is only present/valid with string columns.
     * - `unsigned` Whether the column is an unsigned column.
     *   This is only present/valid for integer, decimal, float columns.
     *
     * In addition to the above keys, the following keys are
     * implemented in some database dialects, but not all:
     *
     * - `comment` The comment for the column.
     *
     * @param string $name The name of the column
     * @param array<string, mixed>|string $attrs The attributes for the column or the type name.
