ghostface on "[Plugin: Participants Database] Text overlapping columns/how do I widen columns"

Hello,

I seem to be having a few issues with text bleeding into other columns and overlapping text, is there anyway to fix this? For the download link, would it be possible to simply set the text as a default value such as 'download'?

Many thanks.
