优化 JavaScript 代码：使用循环代替 find 方法

以下是不使用 find 方法修改后的代码：

for (let i = 0; i < this.tableData.length; i++) {\n const item = this.tableData[i];\n let suggestedItem = null;\n for (let j = 0; j < suggestedDataList.length; j++) {\n const suggested = suggestedDataList[j];\n if (item.assesseeId === suggested.assesseeId) {\n suggestedItem = suggested;\n break;\n }\n }\n if (suggestedItem) {\n item["improvementContent"] = suggestedItem.improvementContent || "";\n }\n}
