Tabs allow the next piece of text to be indented, and more importantly, aligned to a common column within the output. Tabs can be set to align on the left, on the right, or centrally. They can be quoted either as an absolute column number from the left of the drawing area, or as relative tabs from the current position. Relative tabs are useful when you simply need spacing rather than alignment.

Although you can choose a simple value using either the slider or by typing in the number, you can also use expressions to calculate a value. If, for example, you were trying to break up rows of data into three columns, you might use an expression such as:
4 + ( ($iRowNumber % 3) * 12)

to ensure that the data from consecutive rows tabs across appropriately to each column.
You can also change the tab size from here and it stays in effect until to change it again or reset it to default. There are four ways to specify the new tab size:

Default (5mm) puts the tabs back to the default of 5 mm (38 tab stops in portrait, 56  in landscape).
Set to number of tab stops puts the tabs as close as possible to nn tabs (you will always get at  least that many).
Set to % of drawable width puts the tabs to nn% of the entire width between margins (as close as it can get).
Set to mm puts the tabs to nn millimetres (as close as it can get).
Tab positionThe sample page view shows vertical lines indicating all the available tab stops. Use these to aid you in determining where an item of text should be placed. Simply hover the mouse over a tab stop and a small tool tip will display showing you its tab stop number.

Also, there is a tab ruler at the bottom of the editor showing the tab stop positions and every other tab stop value is indicated, like this:

Note that when using the editor, the editor will always show feint lines for the default tab stops. Currently it is not possible to show the tab lines per row of text - this may change in the future. Any rendered text, however, will show the correct alignment based on the current tab settings.
You must press Insert (or Update if editing an existing command) for your changes to be applied to the current script in the editor.
