For data obtained on HTML, JSON or TABLEDATA-serialised VOTable format you can view it on a pop-up window. This will allow you to peek into the data. Please be aware that when plenty of rows/columns are queries this might be slow and/or hard to navigate as it will render on the client side. In any case, downloading the data is suggested.
You can quickly paste the name
of a column or a table into the ADQL query text
just by clicking on its name on
the lists below (please be aware
of the spacing).
