如何避免大HTML表格中的文字分页（打印/ PDF）？

Question

我有以下一个HTML文件（包括款式/脚本）：FQ.html

我有以下问题：

我已经在解决方案的尝试迭代，为其最新尝试有以下一些CSS ...

@media print{ 
    @page { 
    size:1080px 1080px; 
    margin: 0px; 
    } 
    .page-break-before { page-break-before: always; display:block; width:200%;} 
    .page-break { display:block; page-break-after: always; width:200%; } 
} 

...和Javascript。

//set viewport height in print mode. 
var height = 780; //screen.height; 
//pick up the total table. 
var table = $('#identification_section > table')[0]; 
//initialize the sum variable with height of title (h2 tag) 
var sum = 24; 
//loop all table rows including child tables 
for (var i = 0, row; row = table.rows[i]; i++) { 
    //tr is the parent table row which may contain child table. 
    var tr = row; 
    if (tr.offsetHeight > height) { //if row's hight is bigger than viewport height, it contains child table. 
    var child_table = tr.cells[0].children[0]; 
    if (child_table.className=="group-table") { //pick up child table. 
     var child_sum = 0; 
     for (var j=0, subrow; subrow = child_table.rows[j]; j++) { 
     var subtr = subrow; //pick up child table's row 
     child_sum += subtr.offsetHeight; // sum up the row's height. 
     if (child_table.rows[j+1]!=null) //check if next row is existing, not end row. 
      if (child_sum + child_table.rows[j+1].offsetHeight > height) { // if (sum of table rows so far + next row's height) > viewport height 
      //var temp = subtr.cells[0]; // pick up the first cell of row 
      child_table.rows[j+1].classList.add('page-break-before'); // set the page-break-before to next row. 
      subtr.classList.add('page-break'); // set the page-break to current row 
      child_sum = 0; // set the sum 0 for next page calculation. 
      } 
     } 
    } 
    } 

    sum += tr.offsetHeight; // sum up the height of parent rows. 
    //tr.cells[0].setAttribute('style', 'height:'+tr.offsetHeight+'px'); 
    if (table.rows[i+1]!=null) // check if there is next row. 
    if (sum + table.rows[i+1].offsetHeight>height) { // if sum + next row'height is bigger than viewport row 
     //var temp = tr.cells[0]; 
     table.rows[i+1].classList.add('page-break-before'); //set the page-break-before class to next row 
     tr.classList.add('page-break'); // set the page-break class to current row 
     sum = 0; //set the sum 0 for next page calculation. 
    } 
} 

但是，我仍然处于亏损状态。与其试图避免突破文本，我觉得避免打破文本会更容易。尽管如此，我的尝试解决方案还存在2个或更多问题。其中之一是休息时间太过分了，第二种情况是，有些休息室的宽度似乎不再设定为50％。

防止文本或文本出现中断，最好是文本。

您必须将page-break-before和page-break-after规则应用于文档中的所有元素。

例如，对于表格，您可以使用table tr和类似的选择器。
