Three things from reading it on a real screen.
Column rules. The grid alone was not enough to follow a line across: cells
now carry a right border and the row stretches, so the rules run unbroken
from the header to the bottom of the list. That is what turns rows of text
into a table.
Left-aligned. The previous pass centred the grid inside a maximum width,
which on a wide screen opened a dead margin down the left before the first
callsign - trading the hole in the middle for a bigger one at the edge. Now
it fills the width and the slack lands in the message column, which is the
one that can use it and the one bounded by rules on both sides, so it reads
as a cell rather than a gap.
"CQ CQ PE1NAO JO32" - a green CQ badge in front of a message whose own
first word is CQ. The badge is gone; the word already in the line is picked
out instead, which scans the same and stutters not at all.
