In File.lua the function "tocsv" takes a row of data (in a table) and converts it to a string:
local function tocsv(t, separator, nan_as_missing)
local s = ""
for _,p in pairs(t) do
if (nan_as_missing and p ~= p) then
p = ''
end
s = s .. separator .. escapeCsv(p, separator)
end
return string.sub(s, 2) -- remove first comma
end
However, pairs(t)does not have a guaranteed ordering. As a result, for some (especially large) data sets, the ordering of each row (including the header row) becomes inconsistent from row to row.
Possible solution: ipairs(t) guarantees order, put places constraints on the data format in t (requires it to effectively be a numbered array), and so may not be drop-in replacement without other rework.
