# How can I split a column into multiple rows?

How can I get [1, 2, 3] in the table below to each appear in a separate row within the same column (with a line between each)? THANKS.

• Will it always be that specific column that has to be split? What about the other elements in the row? – Werner Jul 11 '13 at 7:01
• I'd like the other elements in the row just to appear by themselves... though there is one other row that will be split in two... – Teusz Jul 11 '13 at 7:48
