[Qgis-user] Raster Attribute Table

[Marc Bordelon]

I've been using QGIS for about 4 years now. I'm presently running 3.40.10. I've created a DEM raster layer with 15 classes based on 0.5ft contours. I've also created the symbology to reflect these classes, along with an attribute table. The table looks great but I can't edit the table to remove all the columns (with band colors). All I need is the contour breaks along with the colors. 
Is there a way to remove these columns. I can edit the table, but only to add a column not to remove a column. 
If I convert the DEM Raster layer to a Vector layer only 2 columns are converted (id, elevation) none of the others are converted. 
Is there a fix for this or is there another way to get an attribute table to reflect elevation contours along with colors. 
Any help would be greatly appreciated.
