nu-table/ Do footer_inheritance by accouting for rows rather then a f… (#14380)

So it's my take on the comments in #14060 

The change could be seen in this test.
Looks like it works :) but I haven't done a lot of testing.

```nushell
$env.config.table.footer_inheritance = true;
$env.config.footer_mode = 7;
[[a b]; ['kv' {0: [[field]; [0] [1] [2] [3] [4] [5]]} ], ['data' 0], ['data' 0] ] | table --expand --width=80
```

Maybe it will also solve the issue you @fdncred encountered.
