I would use a ready-made solution like this http://datatables.net/
Even if the maximum, turns out only 300 lines, such plug-ins with this table can handle it - quickly, quickly search, beauty is likely to bring not too difficult.
With the width of the table, of course, problems. But I think, or you can combine some fields, such as cell phones:
+7 911 000 00 00
+7 812 000 00 00
Search to cope, and the table on the two columns will have. Full name also. Well, or as advised already - some sort of cards to do.
