Symfony Export Xlsx Laravel Package

add in Table class: getLetter and getIndex

Table::getLetter(27); // 'AA'
Table::getIndex('AA'); // 27

Different experimental classes have been removed. If you have used them, they have been moved to the repository: https://github.com/Denisok94/symfony-export

I have removed various classes that I used to automate the export process in one of my projects. Since I didn't describe their work here, I thought they would be superfluous for others and just take up space. And I decided that it would be better to put them in a separate repository.
