Saiku Table展示数据合并bug修复（二十五）

Saiku Table展示数据合并bug修复

Saiku以table的形式展示数据，如果点击了 非空的字段 按钮，则会自动进行数据合并，为空的数据行以及数据列都会自动隐藏掉。

 

首先我们应该定位问题：

1.查看接口返回值，会发现接口返回都正常，数值没有任何问题，所以我们能清楚的知道与后台没有关系。

2.从页面上定位问题，会发现是table渲染问题 ： /saiku-ui/js/saiku/render/SaikuTableRenderer.js  （如果是编译好的saiku,请找到 saiku-server omcatwebappsROOTjssaiku enderSaikuTableRenderer.js  ）

接下来我们来分析一下问题原因：

1.渲染页面主要是 SaikuTableRenderer.js文件中的此方法：

　　SaikuTableRenderer.prototype.internalRender = function(allData, options)

2.数据内容都存放在<table>标签中，存放内容为 tableContent,tableContent包含所有的数据信息。

js代码里面主要有两层for循环,将数据取出然后以字符串形式拼凑到 tableContent 里面，最后返回到html页面中渲染。

第一次是循环取出行数据信息

  for (var row = 0, rowLen = table.length; row < rowLen; row++) 

第二层是第一层循环中的行数据中取出对应的列数据，然后拼凑为<tr>标记的行数据 rowContent 里面 

 for (var col = 0, colLen = table[row].length; col < colLen; col++) 

3.主要逻辑：

有个boolean类型的 same 标记，用来判断上下文数据信息是否一致，如果一致 same=true,后面就会自动合并

　var same = !headerSame && !isHeaderLowestLvl && (col == 0 || !topParentsDiffer(data, row, col)) && header.value === previousRow[col].value ;

我们主要来看一下这个值：header.value === previousRow[col].value ，意思就是说当前记录列值与上一条记录的列数据相同时，same就为true,让其自动合并

　　自动合并的原理： 将当前记录的此列值置为空

　　　var value = (same ? "<div>&nbsp;</div>" : '<div rel="' + row + ":" + col + '">' + (sameAsPrevValue && Settings.ALLOW_TABLE_DATA_COLLAPSE ? '<span class="expander expanded" style="cursor: pointer;">&#9660;</span>' : '' ) + header.value + '</div>');

不断的循环出当前行的列值，然后将列值拼凑为 rowContent

　　　rowContent += '<th class="' + cssclass + '" ' + (colspan > 0 ? ' colspan="' + colspan + '"' : "") + tipsy + '>' + value + '</th>';

但是下面还有个判断，就是当数据（DATA_CELL 就是标记度量值信息）为空时，saiku会将当前rowContent置为空 

　　

这里三个条件分别是： 

　　用户是否点击了隐藏空数据按钮，也就是我们开头说的 非空的字段 按钮 : option.hideEmpty

　　当前数据信息 header.type属性 是否为 DATA_CELL 类型

　　当前行数据的指标信息是否都为空 （这里上方有代码如判断,我没有全部截取图片）： rowWithOnlyEmptyCells

这样子一来，问题就暴露啦

如果我有两个部门的数据信息，每个部门个 3条数据，第一个部门三条数据都完整，第二个部门第一条数据 指标值都为空，后面两条数据完整

以上逻辑就会这样判断：

　　第一个部门数据正常展示，部门信息相同会自动合并，后面的数据也会正常展示，这个没问题

　　第二个部门的数据，第一条数据 首先部门不会合并到第一个部门，因为当前数据的部门value值与上一条记录的部门value值不同，但是由于cell指标数据为空，所以 rowContent最后就会置为空，相当于不展示此条数据

　　第二个部门第二条数据，部门数据会先判断当前数据的value是否与上一条数据的value相同，结果会发现相同，就会把当前数据的部门信息置为空，后面因为有cell指标数据，所以后面就会展示这条rowContent信息，但是此条数据不完整了，没有了部门名称信息。

　　第二个部门第三条数据同第二条数据一样。

最后我们就会得出这样的结果：

　　第一个部门的数据正常展示

　　第二个部门的数据由于都没有部门信息就会自动合并到第一个部门去展示。

其次我们来讲一下处理方案：

能定位到问题，了解问题原因离解决问题就不远了哈哈哈哈

我这边的处理方案是增加一个boolean类型标记值 headerFlag,用于决定same值，因为其实数据展示的时候是否合并就是在用same的取值

这个headerFlag值定义在两个for循环以外，默认为true,意思就是默认情况下影响数据的合并展示

headerFlag定义：

根据headerFlag的值来定义same值：

当有rowContent被置为空的时候，就将headerFlag标记置为false,就是为了保证当前一行数据为空时，下一次不会自动将部门列信息置为空了

接下来我们就应该开始考虑什么时候讲headerFlag标记转为true了啦

 有以下两种情况我们需要考虑到

>>>  当前行的列数据值不等于上一行数据的列数据值时，表示这是一次新的判断，我们将headerFlag置为true,一切按照原来的一样

>>> 当前tableContent中包含当前行列数据信息时，表示当前列已经存在了，我们可以让它去做合并了，就将headerFlag置为true.

这样子我们就能处理好这个table自动合并的bug了，可能还有更好的办法或者是有全的解法，如有还望不吝赐教哈，多谢~
