我有一个文本文件，其中包含要尝试以表格格式显示的代码。第一栏应该是水果的类型，第二栏应该是食用的数量，第三栏应该是购买的数量，第四栏是购买的日期和时间。
我尝试解析数据并将其记录到控制台。这似乎可以更好地可视化数据，但是老实说，我不知道如何在表中实际显示数据。我真的是Java编码新手，所以我不太了解该语言。
这是我在该网站上的第一篇文章，因此我不确定是否可以正确发布。

您可以将数据解析为可用的格式，如下所示，可以通过多种方式将其安装为表格，例如https://www.npmjs.com/package/tableify或Convert JSON array to an HTML table in jQuery
const parsedData = getData()
.split('\n')
.filter(x => !!x && !x.match(/x{2,}/))
.map(fruitRow => {
const thisSplit = fruitRow.split(/[-–-]/)
return {
fruit: thisSplit[3].replace(/\s+/g, ''),
eaten: thisSplit[4].match(/\d+/)[0],
bought: thisSplit[6].replace('\n', '')
}
})
.filter(x => !!x)
console.dir(parsedData)
function getData() {
return data = `

您需要将文本转换为JSON格式，然后可以使用AJAX Call将JSON文本轻松呈现到表中。
