[WB19] Memory Table

I'm researching something... and found that I need to program a "memory table" which sounds different than adding a "table control".

In this thread,

Guenter understands there's a difference...

"Hi Mauricio, it's been HFSQL C/S with HFilter(..) applied but I decided some minutes ago to re-do the Table as a Memory Table and to feed it by TableAddLine(..) because some additional problems appeared."

Could someone explain, or show me an example of a "memory table" please?
