Such tables can be implemented either by using Java Script on the client, or with a scripting language like PHP on the server. The second option also allows you to cache query results.

Such tables can be implemented either by using Java Script on the client, or with a scripting language like PHP on the server. The second option also allows you to cache query results. Two examples using Java Script are:

Web page with a table containing English musicians (Only works with Firefox)
Web page with a table containing German cities (Only works with Firefox)

Many DBpedia properties have numeric values, so DBpedia data can also be used as input for spreadsheet calculations, for example, using the Objectsheet Java Script visual data environment.

Retrieve the birth and death dates of people, and calculate their lifetime from the query results (Only works with Firefox; requires signed.applets.codebase_principal_support = true in the Firefox configuration)

If you choose to query DBpedia from within the browser, you can also think about using Exhibit, which is a nice Java Script library for visualizing structured information. Exhibit takes JSON data as input, and the DBpedia.org SPARQL endpoint can produce SPARQL/JSON as output, so Exhibit can be used to visualize DBpedia SPARQL query results.
The link below leads to Exhibit visualization of one SPARQL query result:

Display all persons who were born in London
