Horizontal Tabs
Horizontal tab stops are associated with columns, not absolute physical positions.
Changing character spacing will change the physical position of the tab stops.
Default tab stops are set at every eighth column, i.e. column 9, 17, 25, 33, 41, etc. If
different tab stops are to be set, the default tab stops should first be cleared.
Horizontal Tab HT
Advances to the next horizontal tab stop. If no tab stop exists between the active
column and the right margin, the HT will be ignored. Default tab stops are set at
every eighth column, i.e. column 9, 17, 25, 33, 41, etc. Different tab stops may be set
with ESC H, ESC 1, or ESC [ n1 ; n2 ; ... nx u.
