react各个子元素绑定气泡以及数组循环创建元素

render: (text, cell) => {
        if ((cell.bill_type == 1310 || cell.bill_type == 1318) && cell.info.ladder_coeff && cell.info.ladder_coeff !== []) {
          const ladder_coeff = 

          {
            Object.keys(cell.info.ladder_coeff).map((itemKey,item) => {
              return 
{itemKey + ' : ' + cell.info.ladder_coeff[itemKey].toString()}
            })
          }
          
          return (
            

              {text}
              
                
              
            
          )
        } else {
          return text
        }
      }
