Dusted this off for a use case where adding table row numbers server-side is not an option and JS is overkill:

If there is an empty cell starting a row, which is not a row header, then it inserts a counter (which starts at 0 so the row header gets excluded from the count).

```
table {
counter-reset: rowNum -1;
}

tr {
counter-increment: rowNum;
}

tr td:first-child:empty::before {
content: counter(rowNum);
}
```
