IOFactory not loading all columns of csv file when header row missing

[fsuoj]

This is:

• a bug report
• a feature request
• not a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Reader should load all columns from a csv file even if columns are blank

What is the current behavior?

When reading a csv file where the last column is not filled in, then the array key is not added to the array.

What are the steps to reproduce?

Create a text file with 4 columns and no header row with comma delimited data
john,doe,,
mary,jane,,

pass the file name and path to $inputFileName

$inputFileType = IOFactory::indentify($inputFileName);
$reader = IOFactory::createReader($inputFileType);
$spreadSheet = $reader->load($inputFileName);
var_dump($spreadSheet[1]);
die();

Results of var_dump(); will only return the first two keys and not the final two keys.
array(2) {
[1]=>
array(2) {
["A"]=> string(4) "John"
["B"]=> string(3) "Doe"
}
[2]=>
array(2) {
["A"]=> string(4) "Mary"
["B"]=> string(4) "Jane"
}
}

Change the data to be the following:
John,Doe,A,1
Mary,Jane,A,2

Then you will see the full array of data in the var_dump(); results.
array(2) {
[1]=>
array(4) {
["A"]=> string(4) "John"
["B"]=> string(3) "Doe"
["C"]=> string(1) "A"
["D"]=> int(1)
}
[2]=>
array(4) {
["A"]=> string(4) "Mary"
["B"]=> string(4) "Jane"
["C"]=> string(1) "B"
["D"]=> int(2)
}
}
