Editing Tables

Even if you never create a table from scratch, you still need to understand the basic structure to edit a table. Figure 14-13 shows the wikicode underlying a simple table.

Figure 14-13. Here’s a table (top) and its underlying wikicode (bottom). The wikicode is split into seven chunks by six blank lines, for ease of understanding. You don’t usually find blank lines in the wikicode between rows of a table, as is the case here. (These blank lines make no difference in what the reader sees.)

Here are the elements of the wikicode that makes up a table:

• 1. A table always begins with “{|”. In this case, an optional parameter, class="wikitable”, has been added. That parameter tells the software to do standard table formatting, such as shading the top row.

• 2. This line adds an optional caption (starting with “|+”).
