my personal preference for nested table style is:
rt = {}
local t = {}
t[pa1] = va1
t[pa2] = va2
rt[var] = t
var="eek"
local t = {}
t[pa1] = va1
t[pa2] = va2
rt[var] = t
if it's in a loop (i.e. the above is unrolled) because it's cleaner in
my view (less "dereferences") and saves table accesses
or even better
rt = {
[var] = {
[pa1] = va1,
[pa2] = va2,
},
...
}
