javascript - 如何在打印时正确对齐文本

问题描述

我有一个只有一行的 HTML 表，当用户从中选择任何项目时，第一列会自动完成。

我正在填充相应的字段，因此在填充所有数据后，我试图在用户单击时将表的某些列数据对齐print。

我正在使用@media print，但它没有做任何事情

console.clear()

const data = [ //data to populate Item Name search input field
  {
    "ItemName": "Butter"
  },
  {
    "ItemName": "Rice"
  },
  {
    "ItemName": "Milk"
  },
  {
    "ItemName": "Ice Cream"
  },
  {
    "ItemName": "Curd"
  }
]

const data1 = { // this data will be dynamic but for now to test i am using this single data
  butter: {
    "ItemName": "Butter",
    "ItemCode": 400564,
    "PurRate": 8,
    "DiscAmt": 6,
    "gstPercentage": 35,
    "gstAmt": 5
  },
  rice: {
    "ItemName": "Rice",
    "ItemCode": 400565,
    "PurRate": 3,
    "DiscAmt": 2,
    "gstPercentage": 20,
    "gstAmt": 8
  },
  milk: {
    "ItemName": "Milk",
    "ItemCode": 200569,
    "PurRate": 1,
    "DiscAmt": 1,
    "gstPercentage": 50,
    "gstAmt": 2
  },
  'ice cream': {
    "ItemName": "Ice cream",
    "ItemCode": 800002,
    "PurRate": 16,
    "DiscAmt": 2,
    "gstPercentage": 15,
    "gstAmt": 2
  },
  curd: {
    "ItemName": "Curd",
    "ItemCode": 100289,
    "PurRate": 9,
    "DiscAmt": 1,
    "gstPercentage": 12,
    "gstAmt": 4
  },
}

var totalAmount = "";
var unitQuantity = "";


function rowappend(tbody) { // this one is appending row{

  const markup =
    `<tr>

  $(tbody).append(markup);
  setTimeout(() => $("[name=itemNametd]", tbody).last().focus(), 100);

  const itemName = data.map(value => { //using autocomplete to for searching input field
    return value.ItemName;
  });
  $("[name=itemNametd]", tbody).last().autocomplete({
    source: itemName,
    autoSelectFirst: true,
