You can style your fonts in the same way you would in any ordinary word processor. Start by adding text to the template field, select your text and select the desired options in the toolbar.

Tables are great for adding structured information to your contract or invoices. Add your table through the toolbar and select the amount of rows and columns you need.
You can change the width of the columns by pressing your cursor on the border you want to resize and drag it to the left or right.

Adding a new column or row in your existing table can also be done with the toolbar available when editing the table. Here you can edit table properties, remove or add rows and columns or delete the whole table.

Using the table properties panel you can add cellpadding or change the width and color of the border.
