How can I read existing style from existing row?

[cuong02n]

1. I cannot find how to read color, font, size in existing ReadableWorkbook.
2. My problem very simple: read style of a row, and then copy all to below rows and can modify the value of some cells.

My existing workbook

I want my output like this (The color, font, size of first row was applied to another rows.)

I am using apache poi, but I want to try fastExcel for performance.
