复杂表格设计数据格式

[biaochenxuying]

1. 表头设计

原理：
和多叉树的原理类似，参考了它的展示形式。

表头说明：
如果没有孩子节点就只返回如下一个字段：

• name ：名字

如果有孩子节点，就把数据加在children里面，层层嵌套，返回字段如下：

• name ：名字
• children : 孩子节点

数据结构格式，参考如下代码：

headerData:[
            {
                name: '地区',
            },
            {
                name: '总数据',
                children: [
                    {
                        name: '数据1',
                        children: [
                            {
                                name: '数据11',
                                children: [
	                                {
	                                    name: '数据111',
	                                },
	                                {
	                                    name: '数据112',
	                                }
                                ]
                            },
                            {
                                name: '数据12',
                                children: [
	                                {
	                                    name: '数据121',
	                                },
	                                {
	                                    name: '数据122',
	                                }
                                ]
                            },
                            {
                                name: '数据13',
                                children: [
	                                {
	                                    name: '数据131',
	                                },
	                                {
	                                    name: '数据132',
	                                }
                                ]
                            },
                            {
                                name: '数据14',
                            },

                        ]
                    }
                ]
            }
        ];

表头的宽高方面，前端计算，后端不用管，按照如下格式返回数据即可。

#2. 表格数据格式
每一项按照表头展示的顺序返回，通过数组的形式
返回一个参数：

• bodyData：总数据

数据结构格式参考代码如下：

bodyData:[
        ["地区最先","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"],
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"], 
        ["地区","数据111","数据112","数据121","数据122","数据131","数据132","数据14"], 
        ["地区最后","数据111","数据112","数据121","数据122","数据131","数据132","数据14"], 
    ]

#3. 效果
如上表头与表格数据代码生成的效果如图：

4. 代码

语法高亮用到 codemirror 插件

/**
 * 递归遍历 格式化数组
 * @param { Array } paramArr 目标数组
 * @param { Number } level 层级
 */
export function formatArray(paramArr, level) {
  let levelFirst = Number(level)
  const arr = []
  let childArr = []
  for (let i = 0; i < paramArr.length; i++) {
      let obj = {}
      for (let j in paramArr[i]) {
          if (j != 'children') {
              obj[j] = paramArr[i][j]
          }
          obj['level'] = levelFirst
          obj['width'] = getLeafCountTree(paramArr[i])
          if (!paramArr[i].children) {
              obj['childrenNumber'] = 0
              // LeafNode: 叶子节点就是树中最底段的节点
              // obj['isLeafNode'] = true
          } else {
              // obj['isLeafNode'] = false
              obj['childrenNumber'] = paramArr[i].children.length
          }
      }
      arr.push(obj)
      if (paramArr[i].children) {
          let lev = Number(levelFirst) + 1
          childArr = childArr.concat(formatArray(paramArr[i].children, lev));
      }
  }
  let endArr = arr.concat(childArr)
  return endArr
}

/**
 * 获取 节点的所有叶子节点个数
 * @param {Object} json Object对象
 */
export function getLeafCountTree(json) {
  if(!json.children){
      return 1;
  }else{
      var leafCount = 0;
      for(var i = 0 ; i < json.children.length ; i++){
          leafCount = leafCount + getLeafCountTree(json.children[i]);
      }
      return leafCount;
  }
}

// json对对象字符串的格式化，美化
export function  jsonFromat (text_value){
  　　if(text_value == ""){
     　　alert("不能为空");  
     　　return false;
  　　} else {
          var json=eval('(' + text_value + ')');
          text_value=JSON.stringify(json);
          var res="";
          for(var i=0,j=0,k=0,ii,ele;i<text_value.length;i++)
          {//k:缩进，j:""个数
              ele=text_value.charAt(i);
              if(j%2==0&&ele=="}")
              {
                  k--;                
                  for(ii=0;ii<k;ii++) ele="    "+ele;
                  ele="\n"+ele;
              }
              else if(j%2==0&&ele=="{")
              {
                  ele+="\n";
                  k++;     
                  for(ii=0;ii<k;ii++) ele+="    ";
              }
              else if(j%2==0&&ele==",")
              {

                  for(ii=0;ii<k;ii++) ele+="    ";
              }
              else if(ele=="\"") j++;
              res+=ele;        
          }
          return res
  　　}
  }
