I agree with Guido, but I'll suggest you, don't write 'this'
because you'd have to place it yourself, but if you change it for 'name of table
' for example if your table is called 'tableone
'. You will need the following command
this setpos [getpos tableone select 0 , getpos tableone select 1 , 1]
1, it's the correct heigh, for the table.
