+### 支持变量及表达式
+
+> 2.1.0 及以上版本
+
+table-view 的所有属性都支持变量，比如下面的例子通过表达式实现了针对数据进行不同展示
+
+```schema
+{
+  "type": "page",
+  "title": "标题",
+  "data": {
+    "score": 40
+  },
+  "body": {
+    "type": "table-view",

+          {
+            "background": "${score>50 ? '#fef1d2': '#d7f8ff'}",

+              "type": "tpl",
+              "tpl": "分数>50"
+            }
+          },
+          {
+            "background": "${score<100 ? '#fef1d2': '#d7f8ff'}",

+        ]
+      }
+    ]
+  }
+}
+```

 ### 列设置项
 
 列设置项主要是用于控制整列的样式，比如
