I think you're saying that they don't line up correctly in the export, is that right? What format are you exporting to?
In your report, if you have column headers, make sure that you line up the data field with the left-hand side of the column header. Also, if you're exporting to Excel, your best bet is to use the "Excel - Data Only" export.
If you're trying to combine two fields together, one of the easiest ways is to put a text box on the report and put the fields inside the text box with a space between them. If you put them in two separate fields outside of a text box, you'll get extra spaces between the two and it will look something like this:
Mr. John Smith
Mrs. Judy Jones
If you put them in a text block, they'll look like this:
Mr. John Smith
Mrs. Judy Jones
