Table elements conform a structure, so makes no sense formatting a table without rows and cells

Visual structure of a table (table, tr, th, td)

This is caption space

This is tr1 and th1 in thead space	This is tr1 and th2 in thead space
tr1 and td1 in tbody	tr1 and td2 in tbody
tr2 and td1 in tbody	tr2 and td2 in tbody
tr1 and td1 in tfoot	tr1 and td2 in tfoot

Semantic structure of a table (thead, tbody, tfoot)

This is caption space

This is thead space
Tbody here
And finally, tfoot at the bottom

Full table with th and td
