/**
* It's a utility that provides a convenient way to create column schema for use with {@see Schema}
* for MSSQL Server.
*
* It provides methods for specifying the properties of a column, such as its type, size, default value, and whether it
* is nullable or not. It also provides a method for creating a column schema based on the specified properties.
* For example, the following code creates a column schema for an integer column:
* ```php
* $column = (new Column(SchemaInterface::TYPE_INTEGER))->notNull()->defaultValue(0);
* ```
* Provides a fluent interface, which means that the methods can be chained together to create a column schema with
* many properties in a single line of code.
