Help:Wiki University Wikitext--Tables - Column Spans

Spanning columns in tables
This ability to span columns is especially useful when separating sections of one table into different topics.
 * When we create tables, sometimes we want a cell to cover more than one column like in the following example:
 * NOTICE the first row consists of two cells, each spanning two cells of the following row.

How to span columns

 * If we want to span two columns, for example, we use a class called "colspan" like so:
 * colspan="2"


 * NOTICE the "2" represents the number of columns to span.
 * This coding is inserted right after the pipe or explanation marks like so:
 * | colspan="2" style="width:50%; ......." | Foods that have a .......

Here is the coding for the first three rows of the above table:
 * NOTICE again the location of the class "colspan."
 * NOTICE that the new row only has two cells, but each cell has a "colspan" in it. The two colspans cover the four cells in the next row.

Columns have to add up

 * Make sure that the columns you span add up to the total number of cells in the next row.
 * If you span a total of four columns or cells, you must have two colspan="2" in the preceding row otherwise you will get how knows what!

Restrictions

 * You cannot create sortable tables with colspans.
