FILTER 函数

FILTER函数可以根据定义的条件过滤一系列数据。

<p>FILTER函数基于布尔数组来过滤数组。</p> <pre><code class="hljs js language-js">=FILTER(array, include, if_empty?) </code></pre> <table border="1" style="border-collapse: collapse;width:90%;"> <tbody> <tr> <th style="width: 20%;">参数</th> <th style="width: 10%;">必需</th> <th style="width: 70%;">描述</th> </tr> <tr> <td>array</td> <td>是</td> <td>要进行过滤的数组或区域</td> </tr> <tr> <td>include</td> <td>是</td> <td>一个布尔数组,其高度或宽度与要进行过滤的数组相同</td> </tr> <tr> <td>[if_empty]</td> <td>否</td> <td>如果所包含数组中的所有值均为空(filter结果为空)的返回值</td> </tr> </tbody> </table> <p><strong>注意:</strong> </p> <ul> <li>FILTER 函数仅在<code>allowDynamicArray</code>为true时有效。</li> <li>FILTER 函数将返回一个数组,如果该数组是公式的最终结果,则将溢出。</li> <li>如果您的数据集有可能返回空值,请使用第3个参数([if_empty])。 否则,将导致“ #CALC!”错误。</li> <li>如果<code>include</code>参数的任何值是错误(#N/A,#VALUE等)或无法转换为布尔值,则FILTER函数将返回错误。</li> </ul>
