This is what I use for making tables like you are looking for:

;; Set up a blue=negative, red=positive color scale. The
;; middle of the scale is black:
red = [bytarr(128), 2*bindgen(128)]
green = bytarr(256)
blue = [2*reverse(bindgen(128)), bytarr(128)]
color_table = 0
tvlct, red, green, blue

;; Set up a blue=negative, red=positive color scale. The
;; middle of the scale is white:
H = [replicate(240.0, 128), replicate(360.0, 128)]
S = 2*[reverse(findgen(128)), findgen(128)]/255
V = fltarr(256)+1

tvlct, H, S, V, /hsv
tvlct, R, G, B, /get
red = R
green = G
blue = B
color_table = 0
tvlct, red, green, blue
