Can you select the max of a group by and mach it to another table?

Question

I can't get my little head around this one. I have 2 tables
table 1:
T1ID col1 col2 col3
1 a t e
2 g y a
3 h r p
4 f u w
and table 2 that has many entries from table 1
Table 2:
T1ID ID col1
1 3 Y
1 2 M
1 1 H
3 2 W
3 1 E
I want the contents of table 1 with the value of col1 from table 2 where the ID is the highest?
so returning table 3:
ID col1 col2 col3 col1_from_table_3
1 a t e Y
2 g y a
3 h r p W
4 f u w
is this easy to do with a select statment?
Thanks for all of you help(in advance)
