Introduction to tables
How and why
Review of what you've learned
It is common to want to edit an existing table by adding just one extra column or row of information.
Adding a row
To add an extra row into a table, you'll need to insert an extra row break and the same number of new cells as are in the other rows.
The easiest way to do this in practice, is to duplicate an existing row by copying and pasting the markup. It's then just a matter of editing the cell contents. Make sure that you preserve the end of table markup,
|}, below the last row of the table.
Adding a column
To add an extra column to a table, you'll need to add a single extra cell in the same position to each row.
Preview your changes
Previewing your edits is especially important for tables; it is easy to make a minor error that breaks table formatting.
