and if it does, then can someone please tell me what kind of algorithm ConTeXt uses  for these?

???

In TeX you can not have multi page tabular unless you program something. I want to know about the ConTeXt algorithm of doing this.  In LaTeX there are two packages longtable and suopertabular each with advantages and disadvantages so I have been interested to see how ConTeXt handles multipage tabular.
