Column width
In table it is possible to easily change the column width. To manually change the width of the column you need to capture the right column edge using mouse and move it into a new location.
It is also possible to automatically adjust the column width in such a way that this width is as small as possible (i.e. so that the longest number or text that appear in this column should fit in it (without wrapping)). In order to narrow the column width, just double-click on the line separating the columns (at a height of columns' header). You can also use a shortcut Ctrl+Shift+"+" so as to minimize the width of all columns at the same time.
Changing columns order
A user can change the order of columns by placing the mouse indicator on the column header, left-clicking and holding the mouse button and moving the column into a new location.
