Just remember [td] = table divide and [tr] = table row.
End ([/tr]) tr when you're done with the row and want to start a new ([tr])
and put [td] when you want to move over a section. It'll start coming naturally!
Sometimes it's easier to make tables in excel. You can see the rows and columns much easier. I do that and then put "text here" for the parts that will have information. It's so much easier to replicate each row's table code in excel cells.
