如果要对行加颜色，就要在创建列的时候，对每一个列进行判断，然后再赋值，相当于对每一个cell的字体颜色进行赋值。
因为this.getTableRow().setStyle("-fx-text-fill: #006464;"); 并不好用，而this.getTableRow().setStyle("-fx-background-color: "+"#F00FF6");就可以。
是不是Javafx2的bug呢？部分代码如下：
public TableView initTable(JSONArray tablecolJson,JSONObject tableinfo) {
//JSONArray tablecolJson,JSONObject tableinfo,JSONObject tablePage
JSONObject jsonObject = null;
table = new TableView<>();
String twidth = (String)tableinfo.get("width");
String theight = (String)tableinfo.get("height");
String tboder = (String)tableinfo.get("boder");
String ttop = (String)tableinfo.get("top");
String tleft = (String)tableinfo.get("left");
String tisselect = (String)tableinfo.get("isselect");
String tselectstyle = "";
if("true".equals(tisselect)){
tselectstyle = (String)tableinfo.get("selectstyle");
}
for (int j = 0; j < tablecolJson.size(); j++) {
jsonObject = (JSONObject)tablecolJson.get(j);
String id = jsonObject.get("id").toString().toUpperCase();
String title = (String)jsonObject.get("title");
String width = (String)jsonObject.get("width");
if(id==null||id.equals("")){
System.out.println("未设置列id，请重新设置!");
return null;
}
if(title==null||title.equals("")){
title = "请输入标题名";
}
if(width==null||width.equals("")){
title = "60";
}
tableColu = new TableColumn<>(title);
tableColu.setCellValueFactory(new MapValueFactory(id));
tableColu.setCellFactory(new Callback<TableColumn, TableCell>() {
public TableCell call(TableColumn param) {
return new TableCell<String, String>() {
ObservableValue ov;
@Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (!empty) {
ov = getTableColumn().getCellObservableValue(getIndex());
if(getTableRow() != null&&!ov.equals("")){
Map<String,String> vmap = (Map<String,String>)this.getTableRow().getItem();
boolean colorFlag = false;
if(vmap.get("TEXT_COLOR")!=null){
if(!vmap.get("TEXT_COLOR").equals("")){
this.setStyle("-fx-text-fill: "+vmap.get("TEXT_COLOR"));
colorFlag = true;
}
}
if(vmap.get("BACKGROUND_COLOR")!=null){
if(!vmap.get("BACKGROUND_COLOR").equals("")){
if(!colorFlag){
this.setStyle("-fx-background-color: "+vmap.get("BACKGROUND_COLOR"));
}else{
this.setStyle("-fx-background-color: "+vmap.get("BACKGROUND_COLOR")+";"+"-fx-text-fill: "+vmap.get("TEXT_COLOR"));
}
}
}
}
setText(item);
}
}
};
}
});
tableColu.setPrefWidth(Double.valueOf(width));
table.getColumns().add(tableColu);
}
if(ttop==null||ttop.equals("")){
ttop = "190";
}
if(tleft==null||tleft.equals("")){
ttop = "20";
}
AnchorPane.setTopAnchor(table, Double.valueOf(ttop));
AnchorPane.setLeftAnchor(table, Double.valueOf(tleft));
return table;
}
