As stated by Christian in his comment, this is unfortunately impossible.
However, from patch 8.1.1564, there's an option that could solve this problem.
We can merge the signcolumn
and the line numbers.
:set signcolumn=number
From the help (:h 'signcolumn'
):
'signcolumn' 'scl' string (default "auto")
{not available when compiled without the |+signs| feature}
Whether or not to draw the signcolumn. Valid values are:
"auto" only when there is a sign to display
"no" never
"yes" always
"number" display signs in the 'number' column. If the number
column is not present, then behaves like "auto".
This is what it could look like:
