New Post: Problem setCellValueExplicit with PHPExcel_Cell_DataType::TYPE_STRING

Possible values are for example:
DV201030
00060601
CH123456
156782222ANE
VN9721782A
0000567844B
N.A.
TBD
....

is there a possibility to show the leading zeros with this kind of values

FYI The Kollation is utf8_general_ci in the MySql database
