Nice job @chienandalu but when testing with purchase order lines containing taxes from different groups (for example 21% VAT and 10% VAT), the report Request for quotation does not display the tax column, even though it should appear in this case.
Additionally, attempting to print the purchase order using “Print → Purchase Order” raises a traceback instead of generating the PDF.

Traceback (most recent call last):
  File "<777>", line 1011, in template_777
  File "<777>", line 993, in template_777_content
  File "<777>", line 482, in template_777_t_call_0
KeyError: 'doc'

The above exception was the direct cause of the following exception:

@Gelojr Try it again please. Please note that the RfQ report doesn't show either taxes or prices at all. Only the purchase order document does.

Great work @chienandalu !
The following tests have been successfully performed:

• Test 1: Verified that when all purchase order lines share the same tax group, the tax column is correctly hidden in the report.
• Test 3: Confirmed that section and note lines do not interfere with the visibility logic of the tax column.
• Test 4: Verified that different taxes within the same tax group (e.g., 21% goods and 21% services) still hide the tax column as expected.
• An additional check was made: printing the purchase order using “Print → Purchase Order” raises a traceback instead of generating the PDF.

LGTM! Code review.
