[Qgis-user] Query on Expressions

[damien stephens]

Hi Sashi.
That clears it up, thanks.
I don't use tables in map views and generally just stick with legends, so
you are more advanced than me there.

Having a look, you can put the filter in the filter with box; ie $id>29
Then put the worwrap for the individual column in the attributes menu by
clicking on the formula button  next to the attribute.

See how that goes
