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. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Is there a way to remove these columns. I can edit the table, but only to add a column not to remove a column. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">If I convert the DEM Raster layer to a Vector layer only 2 columns are converted (id, elevation) none of the others are converted. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Is there a fix for this or is there another way to get an attribute table to reflect elevation contours along with colors. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Any help would be greatly appreciated. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Marc J.
