Increase Number of Columns (v2.2)
We had a report which exceeeded the 364 columns that are generated for the spreadsheet in version 2.2. This was producing the error "Invalid cell coordinate 1".
I amended line 65 to increase the number of columns to 676.
I saw that in the master branch the code has changed and looks like it automatically generates the correct amount of columns.
I'm attaching a patch for the changes to the code for version 2.2.civiexportoexcel_more_columns.patch
