How to find value in another table and return value from same row

Hi all

This is my first post here so apolgies if I'm using the wrong sub-forum or anything like that.

I really need some help with the following problem in Excel 2010.

I have two vaery large tables of data:

Table 1 is a long list of unique items in no particular order, each of which belongs to a unique group of items, for example:

Items Group ID
apple
pear
grape
fig
banana
guava
peach
mango

Table 2 lists all the Group ID numbers and in the same row as each Group ID number, shows the names of all the items belonging to that group, one item in each column. Different Groups have different numbers of items in them. For example:

Group ID Item1 Item2 Item3 etc.
214 apple pear grape
33 fig
7 banana guava
59 peach mango

Is there a formula I can use in the second column of Table 1 to look for each item in Table 2 and tell me what group it is in? For example for "apple" or "pear" or "grape" it would look in Table 2 and return the Group ID number "214".

Hope I've explained that clearly and thanks in advance for any ideas.
