针对onLoad事件优化Google表格功能

问题描述

我有一个包含多个工作表的电子表格。打开电子表格时，我希望做一些事情：

trimSheets（e.source）;
protectHeaderRows（e.source）;
protectLockedColumns（e.source）;
hideApplicationMetadataSheets（e.source）;

trimSheets ：修剪工作表中的所有空白行和列

protectHeaderRows ：对包含许多我不想搞砸的数组公式的标题行设置保护。该保护设置为“仅警告”，并且设置了背景和文本颜色。

protectLockedColumns ：工作表上任何带有锁定值“?”（U + 1F512）的列也将受到保护并突出显示。

hideApplicationMetadataSheets ：带有要隐藏的名称模式的工作表（例如'/ ^（Audit：）* /'）

我已经使用类似于以下示例的模式对所有这些进行了处理。完成4个任务之前，完整的onLoad超时超过30秒。下面的示例是10张纸的修剪过程，大约需要5秒钟。

未经处理的工作表迭代速度相对较快（
