If the size of the collection would be a multiple of 10, you could use 
#groupsOf:atATimeDo:, but it's not, so I'd try something like this:

| start end step |
start := 16r000020.
end := 16r00007F.
step := 10.
start to: end by: step do: [ :groupStart |
 	| group |
 	group := groupStart to: (groupStart + step - 1 min: end).
 	html
 		tableRow: [
 			group do: [ :each |
 				html tableHead: each ] ];
 		tableRow: [
 			group do: [ :each |
 				html tableData: each asCharacter ] ] ]
