Table doubled in size due to index, way to remove this duplicate data?

[Josh Irish]

Hi All,

Got a table that is just an index and a telephone number, needs to be queried for a number constantly so put an index on the number field, this makes the table 5GB up from 2.6GB though.

Is there anyway to just have the table save the number fields in order like it does the index, so that I can search it quickly without doubling the size?

Thanks!
