Lansweeper does not have a built-in report called "Other scanning errors" so I'm not sure which report you are specifically referring to. However, I'll use the built-in report "Error: All scanning errors" as an example.
You can move the columns easily by using the report builder and dragging the rows of the fields in the correct order. The top row if the first column in the output.
You can move the rows by dragging and dropping them in the correct order by using the :: icon on the left side.
You can rename columns by giving them an Alias as seen below.
Instructions for adding this report to your Lansweeper installation can be found here: https://www.lansweeper.com/Forum/yaf_postst9882_How-to-run-a-report.aspx#post38309
If you are interested in building or modifying reports, I do recommend:
Reviewing some SQL tutorials, as the Lansweeper report builder is a standard SQL editor. If you know SQL, you know how to build Lansweeper reports as well. This seems like a good tutorial: https://www.w3schools.com/sql/
Making use of the database dictionary, which explains in great detail what each database table and field stores. More information on the dictionary can be found here: https://www.lansweeper.com/Forum/yaf_postst9870_Lansweeper-database-dictionary.aspx#post38296
