When a tablelist is used as a tree widget, one of its columns (specified
by the -treecolumn option) will display the tree
hierarchy with the aid of indentations and expand/collapse controls.
The look & feel of that column is controlled by the
-treestyle option, which includes, among others, the
images used for displaying the expand/collapse controls, the indentation
width, and whether expand/collapse controls and indentations are to be
protected when selecting a row or cell. The Tablelist package chooses
the correct default style depending on the windowing system, operating system
version, and tile theme. The number of supported tree styles has
increased from 16 in Tablelist 5.0 to 25 in Tablelist 5.6:

In the forthcoming Tablelist version 5.7, the tree styles
ubuntu and mint have been adapted to
the Ubuntu Linux release 12.04 and Linux Mint release 13, respectively.
