先来看看展示效果

项目需求

• 展示基础表格
• 在每一列数据中，如果只有正值，则表格左侧为0坐标，以最大值为表格全部宽度，其他按照比例去展示
• 有正负值，需要计算0坐标位置，根据最大值最小值去确定坐标位置，根据正负值展示图形
• 负值图形颜色为红色，正值颜色根据外部传入参数确定颜色，默认蓝色

      width: 160,  //列宽
      hasChart: 'true', //是否展示图形
      chartClass: 'origin', //图形正数据的颜色
      align: 'right'   //列文字居左还是居右
    },

• 表头属性

     name: 表头名称,
      prop:列数据对应的参数名,
      width: 160,  //列宽
      hasChart: 'true', //列是否展示图形
      chartClass: 'origin', //列图形正数据的颜色
      align: 'right'   //列文字居左还是居右
