Antique table with adjustable legs

I was given this end table because the legs were wobbly and it had a crack on the top. When I got it home and cleaned it up I discovered that the legs were not wobbly, they were not placed in the notched holes correctly. (See photo) I am curious as to what period this table is from and any information I can gain from anyone whom might have an idea on what it was made for?

The table is 30 inches in heighth the top table is 14 inches x 14 inches and I am not sure if it is the same kind of wood. The base looks to me to be mahogany(?) and the top of oak(?).

I have done nothing to it but put the legs in the proper holes and wash it off. The top is slightly warped and has a crack through it. There is a label attached to the very bottom that reads" Chitimen Eastman Furniture 03   Burlington , Iowa." The rest of the label is too faded to read.
