Patrick,
I was able to see the table due to your offline help. I expected a community-wise classification in the table.
In any case, it is common place knowledge among Indologists who studied varNa and caste systems that varNa is, to a large extent, textual and what is real is in fact caste. Kshatriya is a varNa category drawn from older Sanskritic texts and used to attribute to individuals of several different tribes and castes who took over roles similar to the ones enlisted as the dharma of the Kshatriyas in the Sanskrit texts. The roles that these tribes and castes took over range from the foot soldier to the emperor. In other words, most of the kings, emperors, soldiers, military officials of all ranks hailed from not the Kshatriya varNa but several different tribes and castes.
Kshatriyization of tribes and castes, its role in the upward mobility of tribes and castes, the concept of Sachchhudras floated during medieval times to 'explain' the Brahma-Kshatriya behaviour and the Kshatriya roles of different 'S'udra' communities, etc. are all beaten track among the Indology and Indian history discussions.
I shall provide you specific examples and references, depending on your purpose and question.
Since it is such a beaten track, many other members of the list may also be able to help you.
