If your column “More Calculating into New Columns.” installation doesn’t transfer names, you can use the steps below to fix this. Clear you old project or open a new QGIS project, and display only the Tablejoin.shp layer that you just created. Right click the Tablejoin.shp layer, open the attribute table and left click on Open Attribute Table Add and open the more_data table, and sort in ascending order on the column named (remember, click on the name until you have an upward BLKGRP pointing triangle) Also sort the Tablejoin.shp attribute table by the BLKGRP attribute. Look at the set of rows, and notice how the columns match in Tabjoin shapefiles. Specifically, to change the name of more_data_1 to HH90, and the name of we’ll want more_dat_6 to HHINCAV As we said earlier, it would be better if QGIS always automatically copied the names after the join, but often it doesn’t. No matter, we can use the Table Manger plugin (Plugins Manage and Install – Plugins Table Manager), the table/pencil icon, usually near the lower left – margin of QGIS: Left click on the Tablejoin layer in the TOC to make it active (it should have a blue or grey bar surrounding it): Click on the Table Manager icon to activate it. Change the names for the two columns, by clicking on a column to activate it (more_data_1), then the rename button on the right, the fill in the new name (HH90) on the popup. Do the same for the more_dat_6 to HHINCAV Save and close the table, ignoring the note about layer styles More Calculating into New Columns
