Thanks, scorpio!
I also found one thing, may be it will be usefull: by SQL request posible to combine folio number and element position like "page.position" (2.B4 or 4.A3).
Add to SQL request text: "..., diagram_position|| '.' ||position AS Position, ..." and in nomenclature table apears column with header "Position" and "page.position" for each elements.

I found the solution by myself. It's posible to change the nomenclature headers by adding to SQL request operator AS.
For my table SQL request is look like this: "SELECT label, comment, designation, manufacturer, quantity, diagram_position, position FROM..." and so on. I write new header name for specified column by adding new name after AS operator like so: "SELECT label AS Item, comment AS Descriprion, designation, manufacturer, quantity AS Qty, diagram_position AS Page, position FROM...".
May be it was usefull.

Hello! I use QET v.0.90 and it's great app for scheme drawing! Good job of developers and translators!
Can someone help me on one thing?
I would like to change the headers on nomenclature table: from "Label" to "Item", from "Folio position" to "Page" and etc. How I can do that by esiest way?
