Steps to reproduce or a small repository showing the problem:

Create a model. The Column decorator must have at least one argument, forcing you to do Column({}) if you don't have any options to specify. Not the end of the world, but also an easy fix with one more overload or changing:

export function Column(options: ColumnOptions): Function;

to

export function Column(options?: ColumnOptions): Function;
