I have a CSV file with xcoord,ycoord and pixel value from DEM. After I import it in QGIS, I take this table. enter image description here

enter image description here

I want to make a raster from this point layer. I tried rasterized (vector to raster), I put exactly the dimensions I want (1028x1310,30x30, taken from masked DEM) but raster cannot be created. I also tried with grid but no result. What is my mistake?
