With CArrays you can only have one specific type for the array (int, float, etc) whereas with a table each column can have a different type (string, float, etc). If you want to replicate this with carray, you would have to have multiple carray's for each type. I think for storing numerical data where querying isn't that important, carrays are just fine. But even if you have to query, you can replicate the indexing behavior for example by adding a second carray with the values you want to index.
