We'll start with how to add a row. Every page will always have at least one row on it, because the last row can never be deleted. So, to add a new row all you need to do is move your mouse cursor to the plus icon on a current row and you will see three options. The second one is 'Add Row'. Click this and a row will be added after the current row.
Adding a column is very similar. Find the row that you want to add a coulmn to and move your mouse cursor to the plus icon. Click on 'Add Column' and a column is added to that row.
Tip: Each row can have its own width and justification
Tip: Rows can be fixed or variable width. This is determined by using pixels (fixed) or percent (variable) when setting the row width
Tip: You can set the width for all rows on a page simultaneously by choosing Row Widths and clicking the All Rows radio button.
