How to write reference to Table in vba

Dear Sirs
I have a problem to write reference to Table.
Normally with a range I would write looping "For Next" like that:

 
For i=1 to range("rgsample").rows.count  
...
next i

how to write it if I need to check rows in Table1
I tried things like: for i=1 to Table1.rows.count and many similar comibnations and nothing works.
I means for me I need to get educated in this field. Please help
