Poi obtains the red font of the Excel cell and the content of the pale blue foreground color.

For Microsoft Excel 97-2003 worksheet (.xls)

If (31 = cell. getcellstyle (). getfillforegroundcolor () // determines whether the foreground color of a cell is pale blue. If (10 = book. getfontat (cell. getcellstyle (). getfontindex ()). getcolor () // determines whether the cell font color is red.

For Microsoft Excel worksheet (.xlsx)

If (0 = cell. getcellstyle (). getfillforegroundcolor () // determines whether the foreground color of a cell is pale blue. If (0 = book. getfontat (cell. getcellstyle (). getfontindex ()). getcolor () // determines whether the cell font color is red.
