Columns adjustment in one row

Question

Hello,
I hope some1 can help me for these.
I am using apex 3.1.2 ver
My first question: how can I put more columns for example 4 columns with heading in one row? when I do, screen is too wide but i do not want scrolling?
e.g
aaaaaaaaaaaaaaa( ) bbbbbbbbbbbbbb ( ) ccccccccccccccccc ( ) ddddddddddd( )
second question?
how can i display second column value based on first column value before saving the page?
e.g. aaaaaaa(1) bbbbbbbb(should display text value based on first column)
for example 1 - abc
2 - def
3 - ghi and so on.
last question? how can i disable the column? should column enable based on other column? e.g if a then second column take value other disabled?
Many thx.
kind regards,

02. Submit the page using any event (such as button press or something). So when you enter details to first item and then press button then page will submit and reload the same page.
03. In the page create a before region process and check whether second item is not null and third item is null then populate third item. Then first item is not null and second item null then populate second item.

Example
if ($x('P16_YYY').value !='SOME VALUE')
  $x('P16_XXX').disabled = true;
}else
  $x('P16_XXX').disabled = false;
}
