Highlight the required columns by clicking and holding the left mouse button
on the column headers (grey and lettered). Then release the button and
place the pointer over the edge of one of the headers and double click. This
will format the columns into their appropriate sizes.
Or, you could follow the same process as above for each column individually;
but instead of double clicking, drag the column to the desired width.
I'm sorry to say Jenn, but as far as I know, you cannot have two separate
widths in one column. You can widen a column as a whole, but not just a
selected portion.
