In my worksheet I've a lot of column and is impossible to make
for 150 column aka 150 source rows.
There's any comman to do this or other workaround?
There is no workaround at the moment, but once we get fixed this work item:
it should be possible to use e.g. getColumnDimension('A:ET')->setAutoSize(true) to autosize each of the columns in the range
This is what you are asking for so there is no need to raise any additional feature request.
