[Javascript] Combining 2 tables

[Paul Cowan]

Hi,

If I have 2 tables say <table id=”table1”> and <table id=”table2”>.  How can 
I through Javascript to combine all the rows from table1 into table2.

Also can I tell whether a table has reached it’s overflow point or if a 
table has it’s scrollbar showing, this if it has an overflow-y value of 
‘auto’.

Thanks in advance.

Paul
