Summary
Review of what you've learned
When you use the 
toolbar button to insert a table, it actually inserts markup text into the article for you to edit. There are two common ways to lay out this markup that you may see around Wikipedia
Data is arranged like a table
This is useful when there aren't too many columns and the cell contents are short (e.g. just numbers). This is the markup layout that the 
button will create.
{| class="wikitable"
|+ Caption
|-
! Header C1 !! Header C2 !! Header C3
|-
| R1C1 || R1C2 || R1C3
|-
| R2C1 || R2C2 || R2C3
|}
Cells are arranged vertically
With lots of columns, or cells with long contents, putting each cell on a new line can improve readability of the markup.
{| class="wikitable"
|+ Caption
|-
! Header C1
! Header C2
! Header C3
|-
| R1C1
| R1C2
| R1C3
|-
| R2C1
| R2C2
| R2C3
|}
Both of the above examples look the same in an article.
| Header C1 | Header C2 | Header C3 |
|---|---|---|
| R1C1 | R1C2 | R1C3 |
| R2C1 | R2C2 | R2C3 |
Whether you've just inserted a new table, or are editing an existing one, changing the text in these cells determines what table displays in the article.
