Pdfmake 在分页时将两行放在一起 table

Question

对于 pdfmake，我有一个 table，其中每条记录使用两行。例如：当 table 中断时，它会按每一行中断。但是，我希望它在 table 中的 2 行之后或之前中断，您将这两行放在一页中。

而不是：

我希望这两行在同一页中。有没有办法确保发生这种情况？我试过使用 pageBreakBefore 函数，但是我对它不是很直观，而且网上也没有很好的例子。

var dd = {
        content: [
    
        'The following table has nothing more than a body array',
        {
            style: 'tableExample',
            table: {
               dontBreakRows:true,
              //  headerRows:1,
                body: [
                    [{text:'Col', colSpan:3, fillColor:'grey'}, {},{}],
                    [{text:'Column 1',fillColor:'blue'}, {text:'Column 2',fillColor:'blue'}, {text:'Column 3',fillColor:'blue'}],
                    ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}],
                                        ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}]
,
                    ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}]
,                   ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}]
,                   ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}]
,                   ['One value goes here', 'Another one here', 'OK?'],
                    [{text:'Description:\n'+'sdfgdhfjsfgvbnfhjfhjfghjgfjgfjfhjfghjgffghjgfasfsjgkfldshgfkld',colSpan:3}]
,


                ],
            }
        },
    ]
    
}

Answer 1

您可以将这些行定义为单独的 table，每行在根 table 中的一行中。这样，行就不会分开，因为它们在 top-level table

中排成一行

Answer 2

你可以这样处理：

pageBreakBefore: function(currentNode, followingNodesOnPage, nodesOnNextPage, previousNodesOnPage) {
  //Here you can change the criteria of pageBreak according to your requirement
  if (currentNode.id === 'myid' && (currentNode.pageNumbers.length != 1 || currentNode.pageNumbers[0] != currentNode.pages)) {
    return true;
  }
  //Here you can change the criteria of pageBreak according to your requirement
  else if (currentNode.id === 'mySecondid' && currentNode.pageNumbers.length != 1) {
    return true;
  }
  return false;
},
