Inserting Tables
To insert an HTML table that lets you position text and images on separate columns, click the “Insert Table” button 
. Specify the number of rows and columns, and click “OK”.
Optionally, you can type the width of the border, the background color (using the #rrggbb syntax), and cell padding and spacing.
You can also change the width of the table by typing the preferred width followed by “px” (pixels) or “%” (percent), e.g. 640px, 300px, 100%, 50%.
Inserting Horizontal Lines
To insert a horizontal line, click the “Insert Horizontal Line” button 
. This is actually all there is to it. Simply select the place in text you want to insert a horizontal line, and click the button.
Indenting Text
Use these two buttons to increase and decrease text indentation: 
. Select text you want to change indentation of, and click the “Decrease Indent” button 
or the “Increase Indent” button 
to control indentation.
Using Lists
You can insert a list of items into text. To insert a bulleted list, click the “Bullets” button 
. For an ordered list, click the “Numbering” button 
. To add an item to the list, type some text, and press the “Enter” key. To end adding items, click the “Enter” button twice in a row.
