Creating dynamic tables

[Treklof]

Hi there,

My name is Folkert van der Wei and I am making an content management system.
Jet I am stuck and perhaps you can help me.
Here is where I am stuck: I want to create a table when someone pushes the button: create table.
When the user pushes the button an windows appears which contains the properties of a table
(borderthickness, ammount of rows, collums, spacing). So far so good. When the user pushes the OK button
the editor has to create an table at the point where the cursor is located.

Here is where the problem is, because how can I read the position of the cursor?
I hope you can help me, because I desperite.

Thanks already
