tabstop width

How to change Tab width in vim?
Say I have a file, columns are separated with single space (or maybe tab). I want to change space to tab (or different Tab width) so that the columns are aligned and nicely padded.
Code:
bob 100 90 30000 40 5
brian 40 30 20 10 10000
rob 10 2 30 40 50
mike 60 88 92 100 80

I tried setting different tabstop width to find the best one as :set ts=4; or :set ts=8, or :set ts=10, but tab width did not change at all in vim. What did I miss? Thanks!

Code:
:set tabstop=number
     and
:set ts=number

will display lines being processed with tab stops set every number columns. It will not convert spaces to tabs. It will not replace sequences of spaces and tabs to make words on various lines magically align as columns in a table.

Thanks Don!
Ah ha! Yes, after I did :%s/\ /\t/g then :set ts=6. It worked!
Does that mean I have to convert all the spaces with Tab first?
Thanks!

The vim or vi utility will display each <tab> found in the input as the number of <space>s needed to reach a tab stop. It doesn't matter whether the <tab>s are put in place before or after you use :set to set the tab stops.

In the post #1 of this thread, it is mentionned :

Code:
dd : Deletes three lines from current cursor position downwards.(also :d)

Shouldn't it be dd : Deletes the current line instead ???

I would also add :
cw : change 1 word begining from current cursor position
ncw : change n word begining from current cursor position
cW: change word treating only whitespace (or line ends) as word delimiters
C : Change the whole line from the current cursor position
D : Delete the current line from current cursor position (leaving in command mode contrary to the C command which do the same but switch to insert mode).
R : Replace (kind of overwrite, this command switch to insert mode)
My 2 cents.
