in MS Word, in order to align decimal numbers according to their decimal point, we need to first set a decimal tab stop and then go to that point via TAB key and start typing, and the alignment will be on the fly as we write
however I need to do that type of alignment in an already typed list of decimal numbers
how can I do that?
I assume you are looking for a quick way to do this to a long list of numbers (if it was short, you could have inserted the decimal tabs manually)
Is each number in the list in a separate line followed by a paragraph mark, with no punctuation
other than the decimal point and possibly commas?
Are there any tabs at present?
Are there any tab stops set at present?
If it's just the list of numbers, each followed by a paragraph or end-line mark, you can do a search and replace, searching for the paragraph or end-line mark and replacing it with a paragraph/end-line mark followed by a tab. This will put a tab before each number (except the first). Then select the whole list and put a decimal tab stop where you want it right/left-wise (I like using the tab bar at the top for this sort of thing, but you can also use the tab dialog).
This list should snap to your tab stop, with all the decimal points directly underneath.
