I've been trying to format the values in a pivot grid when being exported with the plugin(i have premium). I tried setting the exportRenderer to true but it did not seem to use the designated formatter. I tried to use exportStyle.format with one of the preset options and it does work. When i try to use a function with the exportStyle.format, the excel file produces a pop up with the message that the file needs to be repaired. The excel file does not reflect any change to the cell formats, when trying to use a function, but does with a preset. As far as i can tell the exportRenderer true and exportStyle.format with a function are not working. I read the documentation and am not using the exportStyle at the same time as exportRenderer. Are there any known issues/bugs with this or specific limitation.
