The picture below illustrates what I\'m trying to accomplish:
UPD. As you
There doesn’t seem to be any direct CSS method. But you could consider the approach suggested by @CMKanode in a comment. You would need to preprocess the numbers in the column and compute the largest of them (this requires locale-sensitive parsing since you are using a thousands separator), and then you would left-pad the numbers to the same number of characters, using U+2007 FIGURE SPACE as a space that has the same width as digits. And, of course, the column would be declared as centered.
So in the example, “5” would be padded to 5
(assuming you use a normal space as thousands separator; U+2009 THIN SPACE might be better, but it has font issues.
The approach would mean that you need to use a font where digits have the same width (most fonts in computers do) and that contains U+2007.
If the thousands separator were a comma or a period, for example, you would need to use U+2008 PUNCTUATION SPACE in its stead.
In the end, I think this would be excessively complicated. It is probably better to make the column right-aligned but with a suitable left and right padding, selected as a good guess based on the width of the column header and the expected widths of the numbers.
