In my opinion, this does not meet the criteria for a table established in Braille Formats -- it doesn't have row headings. I would align the numbers in each column according to place value.
Braille Formats [Rule 7§1e(2)(a)] says that the first column must begin at the left margin. However, it also says [Rule 7§1e (4) numerals that are aligned by place value generally should be brailled as shown, i.e., placed to align digits, decimals, or commas.
Note also that the numeric indicator would not be used. Rule II§17: In tables whose entries consist entirely of numerals, the numeric indicator must be omitted.
