Delphi XE, FB 2.5

I need to make an array of values from database columns (much like a crosstab) that can be attached to a data source. In my particular case, one database column holds the names of samples sent for analysis, one holds the names of the compounds, and a third hold the reported concentrations. My array would consist of the compound names along the top, names of samples on the left side, and results within the field of the array.

Is it advisable to create a new FB table from a "For Loop" within Delphi and filling the table in the similar fashion?

Thanks
