How to change the type of a cell

[PMime]

In Microsoft Excel you can choose from different types for a single cell or several cells. We would like to use the entry "TEXT" in QXlsx (see the added image).

In the QXslx source code there is the the enum CellType in the class Cell and the method writeString in the class Worksheet.

We applied this in our program, but the type "STANDARD" instead of "TEXT" was shown in MS Excel. Can anybody show me the way to give a special type to a cell? Thanks in advance!
