Table中实现颜色控制:结果：应用到的技术点:Singleton & Supply function & table element中cell的颜色属性具体步骤:STEP 1: 定义context node &定义物料主数据的context node: T_MARA注意：属性中定义成 Singleton属性，表示子节点的与父节点中每个element是一对一的关系.STEP 2: 定义sub node注意：此处supply function的定义：GETCOLORStep 3: 代码编写，实现对颜色的值的获取*ifnecessary,getstaticattributesofparentelementDATAls_node_attributesTYPEwd_this-element_t_mara.DATAls_parent_attributesTYPEwd_this-element_t_mara.parent_element-get_static_attributes(IMPORTINGstatic_attributes=ls_parent_attributes).*datadeclarationDATAls_s_tTYPEwd_this-element_s_t.*TODOcomputevaluesCASEls_parent_attributes-MATKL.WHENA001.ls_s_t-color=01.WHENA002.ls_s_t-color=02.WHENA003.ls_s_t-color=04.WHENOTHERS.ls_s_t-color=00.ENDCASE.node-bind_structure(new_item=ls_s_tset_initial_elements=abap_true).IFsy-subrc=0.ENDIF.STEP 4: 添加table element,并进行颜色的数据绑定STEP5: 关键点，由于supply function是在父节点初始化后调用的，也就是说当往父节点写一次数据后，调用一次supply function,如果重新赋值，必须重新初始化，再赋值，系统才会自动调用supply function，因此，在点击SELECT按钮后，里面代码对父节点重新赋值，在赋值之前，对父节点用方法invalidate初始化一次。DATAlo_nd_t_maraTYPEREFTOif_wd_context_node.DATAlt_t_maraTYPEwd_this-elements_t_mara.lo_nd_t_mara=wd_context-get_child_node(name=wd_this-wdctx_t_mara).DATAs_matnrTYPEREFTOdata.s_matnr=wd_this-m_handler-get_range_table_of_sel_field(i_id=MATNR).FIELD-SYMBOLS:TYPEtable.ASSIGNs_matnr-*TO.CALLMETHODlo_nd_t_mara-invalidate().SELECT*FROMmaraUPTO100ROWSINTOCORRESPONDINGFIELDSOFTABLElt_t_maraWHEREmatnrIN.IFlo_nd_t_maraISNOTINITIAL.IFlt_t_maraISNOTINITIAL.CALLMETHODlo_nd_t_mara-bind_tableEXPORTINGnew_items=lt_t_mara.ENDIF.ENDIF.单元格设置颜色：Web_dynpro-为TABLE的单元格设置颜色 2011-05-12 19:22:58| 分类： SAP开发 | 标签：table ls_s_live data context type |字号大中小 订阅 新增单据时,与系统数据比对,不存在相关数据给出提示,存在则将系统中数据显示,并将匹配的数据着色显示有TABLE中.1.在CONTEXT中新建一节点S_LIVE,保存新增单据.2.在CONTEXT中新建一节点PLAY_LIVE,供LAYOUT中的TABLE绑定用.在PLAY_LIVE下新建一属性cell_design,类型为WDUI_TABLE_CELL_DESIGN.3.在CONTEXT中新建一属性MSG,类型为STRING,供页面显示提示信息用.4.在LAYOUT中新建TABLE,与CONTEXT 中的PLAY_LIVE绑定,将欲着色的COLUMN的CELLDESIGN与PLAY_LIST节点下的CELL_DESIGN属性进行绑定.5.在wddomodifyview中添加如下代码.METHOD wddomodifyview .IF first_time NE abap_true.EXIT.ENDIF.* 页面提示信息DATA lo_el_context TYPE REF TO if_wd_context_element.DATA ls_context TYPE wd_this-element_context.DATA lv_msg LIKE ls_context-msg.* 新增单据DATA lo_nd_s_live TYPE REF TO if_wd_context_node.DATA lo_el_s_live TYPE REF TO if_wd_context_element.DATA ls_s_live TYPE wd_this-element_s_live.* navigate from to via lead selectionlo_nd_s_live = wd_context-get_child_node( name = wd_this-wdctx_s_live ).* get element via lead selectionlo_el_s_live = lo_nd_s_live-get_element( ).* get all declared attributeslo_el_s_live-get_static_attributes( IMPORTING static_attributes = ls_s_live ).* 从数据库中取出相关数据DATA: lt_tab TYPE TABLE OF zcdm_s_play_plan.* DATA: l_tab TYPE REF TO zcdm_s_play_plan.DATA: ls_tab TYPE zcdm_s_play_plan.zcl_wdr_live=get_play_by_procd(EXPORTINGpro_cd = ls_s_live-z_pro_cdplay_date = ls_s_live-z_live_dateRECEIVINGitab = lt_tab).* 与TABLE绑定的CONTEXT列表设置DATA lo_nd_play_list TYPE REF TO if_wd_context_node.DATA lo_el_play_list TYPE REF TO if_wd_context_element.DATA ls_play_list TYPE wd_this-element_play_list.DATA lt_play_list TYPE wd_this-elements_play_list.lo_nd_play_list = wd_context-get_child_node( name = wd_this-wdctx_play_list ).APPEND LINES OF lt_tab TO lt_play_list.* LOOP AT lt_play_list INTO ls_play_list WHERE z_pro_cd = ls_s_live-z_pro_cdAND z_pro_length = ls_s_live-z_pro_lengthAND z_play_date = ls_s_live-z_live_dateAND z_play_time = ls_s_live-z_live_timeAND z_chanl_cd = ls_s_live-z_chanl_cdAND z_subj_cd = ls_s_live-z_subj_cd .ls_play_list-cell_design = 11. 根据内表中行项目,对CELL_DESIGN做设置.MODIFY lt_play_list FROM ls_play_list.ENDLOOP.IF sy-subrc NE 0.lv_msg = 没有查到匹配项.ELSE.lv_msg = 对应数据已标出,请查看.ENDIF.* 显示提示信息lo
