For the benefit of others, this was an administration configuration mistake.
Our admin thought that the column width setting was CHARS, but it appears to be PIXELS.
When the column width was set to 20, it was truncating down to a "C.."
Is there documentation that explains how the pixel widths are prioritized?
E.g. is the width of the leftmost column is enforced by sacrificing all downstream column widths to be narrower if necessary, then the next column is evaluated to see if it fits before sacrificing downstream columns, etc.
We're having a hard time shaping the columns.
TIA
