If I understand correctly, you are worried about obtaining permission to re-publish an illustration (table) that has already been published by someone else. If you have used the data included in a table in a previous publication and are trying to re-publish the table with minimal changes, you will need to obtain permission from the journal publisher of the previous article. Journal websites have information on how to obtain permission for re-publishing illustrations. Once you have this permission, you will need to inform the journal which is about to publish your manuscript.
However, if you are not using the previously published table, and only using the data from the table for your own calculations to create your own table, then no permission is required. Only appropriate reference citation is required, which you have already done.
As for re-using a formula, it is sufficient to include an original formula from a previous paper as a reference, as long as you appropriately cite the reference in your manuscript.
