how in 'vim' editor delete empty lines in visual selection?
V - select lines
:g/^\s*$/d
g: Global command that applies the following command to all lines in the selection that match a pattern.
/^\s*$/: The pattern to match. In this case, it matches all lines that contain only whitespace characters (spaces, tabs, etc.) or are completely empty.
d: The command to execute for each matching line. In this case, it deletes the line.

'virtualedit' 've' string (default "")
global or local to window global-local
A comma-separated list of these words:
block Allow virtual editing in Visual block mode.
insert Allow virtual editing in Insert mode.
all Allow virtual editing in all modes.
onemore Allow the cursor to move just past the end of the line
none When used as the local value, do not allow virtual
editing even when the global value is set. When used
as the global value, "none" is the same as "".
NONE Alternative spelling of "none".
Virtual editing means that the cursor can be positioned where there is
no actual character. This can be halfway into a tab or beyond the end
of the line. Useful for selecting a rectangle in Visual mode and
editing a table.
