[Bug]: When exporting csv of more than 1001 rows, if NO header rows are used, the output file is only 1000 rows about laravel-excel HOT 3 OPEN

Here again to add another detail.

We had success adding WithStrictNullComparision concern.

Using this workaround, the performance are a bit worse than without using it, but we can succesfully export all rows, without using headers, in a situation when a1 cell is always empty

from laravel-excel.

After digging into the rabbit hole for half a day, one genius, a coworker, found the trigger, the root cause of the bug

All starts because we have to export a strange csv file where _the first column of the first line is an empty cell. AND we have no headings in the csv

When your (excellent and unreplaceable) code try to understand if there are data already exported, read the 'a1' cell and checks if it's populated. So it's a false negative, in this case, and the code thinks there are no already exported data, and so, restart from 'a1' and override in the Sheet class the whole already exported data.
