Review of what you've learned
Tables are a commonly used way of displaying information, particularly in articles that contain data. This tutorial aims at providing a guide on how to make tables; if you are looking for the policy on when to use them, see the Manual of Style.
The simplest way to insert a table is with the editing toolbar that appears when you edit a page. Pressing the 
button will open a dialog that allows you to define a table. Once you've chosen the number of rows and columns, the markup text for the table is inserted into the article.
{| class="wikitable"
|-
! Header C1 !! Header C2 !! Header C3
|-
| R1C1 || R1C2 || R1C3
|-
| R2C1 || R2C2 || R2C3
|-
| R3C1 || R3C2 || R3C3
|}
Which looks like:
| Header C1 | Header C2 | Header C3 |
|---|---|---|
| R1C1 | R1C2 | R1C3 |
| R2C1 | R2C2 | R2C3 |
All you have to do is place this where you want it in the article, edit it to match the information you're trying to display, and hit save. You can add more headers by adding more entries in the header section, more rows, or remove headers or rows if you're looking for a smaller table.
