I'm assuming that the array is of type uint8 and represents the red, green, and blue You could use Pillow for this, e.g.

from PyQt5 import QtWidgets, QtGui

from PIL import Image, ImageQt
import numpy as np

# generate data
table = np.zeros((256,256,3), dtype=np.uint8)
for i in range(256):
    table[:,i,0] = i
    table[i,:,1] = i
table[:,:,2] = (2*255 - table[:,:,0] - table[:,:,1]) // 2

# convert data to QImage using PIL
img = Image.fromarray(table, mode='RGB')
qt_img = ImageQt.ImageQt(img)

app = QtWidgets.QApplication([])
w = QtWidgets.QLabel()
w.setPixmap(QtGui.QPixmap.fromImage(qt_img))
w.show()
app.exec()
