Hi Frantisek  (or is it Imagino),
Not sure if you just mean columns A & B.    If it is only
  A&B then you have to make the columns narrower and
  either shrink to fit within cells or  split lines within a cell
  such as using Alt+Enter   which gets you an automatic
  wrap cells.  Wrapping within cells wraps a cell at the
  boundary of a cell.

  Depending on what you've done before
  you might be forced to readjust manually your row heights
  or use a macro.

There are no controls in Excel  that indicate columns or
  rows must be kept together

You can use  file, page setup, page, fit to page
  the pages wide by pages tall are two independent
  parameters,  you can use either, both, or neither.

You can adjust the margins  (page set, page, margins
  or easier in Print Preview)

You can introduce your    own page breaks to break before
 an automatic page break would have occurred.

You can change the font size so you can use a narrower
  column.   You can also use  Shrink to fit for a cell
  under  format, cells, alignment, shrink to fit.

You can adjust the width of a single column by dragging the
  line between the column headers (A,B,C).  You can select
  multiple columns and do them at once for the same width,
  or for all columns by using Ctrl+A and then doing one of
  those.    Any of those can be adjusted automatically by
  double-clicking on the demarcation line between column headers.

  You can do the equivalent for rows, but you are only concerned
  with columns here.
  can double click on any line between the column headers (A,B,C),
  to adjust to the widest.   Or you can do a single column by not
  selecting
