You are looking for wiki coding. Most, except for the most simple is discouraged on profiles because few people really know how to use it and I think we are trying to keep things simple. You can get more fancy on your own profile or on a free space. It looks like you want to make a list after a source citation. To cause the text to line up not in paragraph form, there are about four very simple ways to do it.
1. You can skip two lines instead of one. This wastes space, so it really is better for defining paragraphs.
2. You can create a bulleted list. If you want one with a dot in front of each line with an indent, use an asterisk *
3. To indent, but have each line numbered, use a hash mark #
4. To just indent, use a colon : I usually use two colons to indent a little more. It then lines up nicely with the source citation.
You won't be able to line up the ages like this, but you can use a comma or hyphen to separate it from the name. If you need help with a table, I know how to do that also. But, like I said, they are discouraged for use on profiles.
