I would suggest not to use \starttable at all.
To me the most suitable table environment for such a table is \bTABLE \eTABLE.
It gives you all kind of control over layout, dimensions, frames on and off etc.
I agree natural tables or extreme tables are the better choice for this
table layout but it can be improved.
1. Keep the layout/settings local.
To ensure the \setupTABLE settings don't affect other tables you can
either put \start and \stop at the begin and end of the table, e.g.
\start
\setupTABLE[...]
\bTABLE
...
\eTABLE
\stop
or put the settings in a setup-environment and load them on a pertable
basis, e.g.
\startsetups[fancytable]
\setupTABLE[...]
\stopsetups
\bTABLE[setups=fancytable]
...
\eTABLE
2. Font changes are local to cells
When you apply a font switch to the whole content of a table cell there
is no need to put braces around the text, e.g.
\bTD \bf ... \eTD
can be used without problem. When you make this change for a table
header and the result is bold text there is a even simpler method
because a special cell type exists here, e.g.
\bTH ... \eTH
creates bold text.
3. Simple markup
For natural tables with short texts in each cell there exists a simple
mode which uses \starttable inspired markup with the short \NC and \NR
commands to mark the start of each cell and row.
The example table of the OP can be written like below.
\starttext
\startsetups [tableframe]
\setupTABLE [c] [1] [leftframe=off,width=40mm]
\setupTABLE [c] [2] [rightframe=off, width=60mm]
\setupTABLE [c] [each] [align={lohi,center}]
\stopsetups
\startTABLE[setups=tableframe]
\NC \bf Eons \NC \bf Eras \NC\NR
\NC Hadeon Eon \NC \NC\NR
\NC[ny=4] Archanon Eon \NC Eoarchean Era \NC\NR
\NC Paleoarchean Era \NC\NR
\NC Mesoarchean Era \NC\NR
\NC Neoarchean Era \NC\NR
\NC[ny=3] Proterozoic Eon \NC Paleoproterozoic Era \NC\NR
\NC Mesoproterozoic Era \NC\NR
\NC Neoproterozoic Era \NC\NR
\NC[ny=3] Phanerozoic Eon \NC Paleozoic Era \NC\NR
\NC Mesozoic Era \NC\NR
\NC Cenozoic Era \NC\NR
\stopTABLE
\stoptext
