ALV面向对象方法研究：设定满足条件的单元格的颜色（四）

      还是继续本话题。

      本文讲解如何设定满足条件的单元格的颜色。比如在一张报表里，把成绩这一列小于60分的单元格设定为红色。这种功能很常见！

      1、首先在定义内标的时候记得增加一个栏位放置颜色：      

....
CELLCOLOR TYPE LVC_T_SCOL,
...

      2、在内表修改的时候，将这个栏位附上内容：       

     DATA: W_CELLCOLOR TYPE LVC_S_SCOL.

       IF IT_SFLIGHT-PRICE <= 1000.    "数值小于1000的加红色
          CLEAR IT_SFLIGHT-COLOR.
          W_CELLCOLOR-FNAME = 'PRICE'.   "加颜色的栏位
          W_CELLCOLOR-COLOR-COL = '6'.  "红色
          W_CELLCOLOR-COLOR-INT = '1'.   "颜色加深  0代表不加深
          APPEND W_CELLCOLOR TO IT_SFLIGHT-CELLCOLOR.
       ENDIF.

      3、设定ALV格式的时候：       

*&---------------------------------------------------------------------*
*&      FORM  PREPARE_LAYOUT
*&---------------------------------------------------------------------*
*       TEXT
*----------------------------------------------------------------------*
*      -->PS_LAYOUT  TEXT
*----------------------------------------------------------------------*
FORM PREPARE_LAYOUT CHANGING PS_LAYOUT TYPE LVC_S_LAYO.
  PS_LAYOUT-ZEBRA      = 'X' .
  PS_LAYOUT-GRID_TITLE = TITLE .
  PS_LAYOUT-SMALLTITLE = 'X' .
  PS_LAYOUT-SEL_MODE   = 'A'.
  PS_LAYOUT-INFO_FNAME = 'COLOR'.
  PS_LAYOUT-CTAB_FNAME = 'CELLCOLOR'.  "一定要大写
  PS_LAYOUT-CWIDTH_OPT = 'X'.
  PS_LAYOUT-DETAILINIT = 'X'.
ENDFORM. " PREPARE_LAYOUT

     效果如下图：
