I have to read an Excel file and check if the file format is correct. A way to check do this task is to check if the header cells are correctly merged. For instance, the cells A2 to H5 must be merged, I2 to L2 must be merge, I3 to J3 and K3 to L3 must be
merged. I need to know which cells are merged with a current cell. Is it possible do this with PHPExcel ? Which methods are available to check this ?
