Export file very slow with data have about 100 column

[canhnv-skylab]

When i use PhpSpreadsheetWrapper\ExcelBook and PhpSpreadsheetWrapper\ExcelSheet to export data to file excel, then download file, it take many many time. (over 10m)

This is code, which i use to write data in to cell

$sheet->fromArray($data, null, "B6");

$data have about 1000 row and 100 column

How can I solve it ? Thanks very much!
