DataTables + PDFmake = 彩色 PDF table 个单元格？

Question

我正在尝试从下面的数组 table 中打印一个 PDF 文件，其中包含单词 "Software Engineer" 的每个单元格都显示为蓝色，包含 "London" 的单元格显示为红色。想用一个循环来做到这一点，逐一扫描所有行或列（不是特定的行或列）。但是我根本无法让它工作，并且开始放弃。我想这与 each() 方法有关？

each()

Table I am using

var editor; // use a global for the submit and return data rendering in the examples

$(document).ready(function() {
    editor = new $.fn.dataTable.Editor( {
        ajax: "../php/staff.php",
        table: "#example",
        fields: [ {
                label: "First name:",
                name: "first_name"
            }, {
                label: "Last name:",
                name: "last_name"
            }, {
                label: "Position:",
                name: "position"
            }, {
                label: "Office:",
                name: "office"
            }, {
                label: "Extension:",
                name: "extn"
            }, {
                label: "Start date:",
                name: "start_date",
                type: "datetime"
            }, {
                label: "Salary:",
                name: "salary"
            }
        ]
    } );

    $('#example').DataTable( {
        dom: "Bfrtip",
        ajax: "../php/staff.php",
        columns: [
            { data: null, render: function ( data, type, row ) {
                // Combine the first and last names into a single table field
                return data.first_name+' '+data.last_name;
            } },
            { data: "position" },
            { data: "office" },
            { data: "extn" },
            { data: "start_date" },
            { data: "salary", render: $.fn.dataTable.render.number( ',', '.', 0, '$' ) }
        ],
        select: true,
        buttons: [
            { extend: "create", editor: editor },
            { extend: "edit",   editor: editor },
            { extend: "remove", editor: editor }
        ]
    } );
} );

Answer 1

看看 this 示例，如果年龄低于 40 岁，它会更改 PDF 中的单元格。类似的方法也适用于您。

代码的关键部分是这样的：

buttons: [
  {
    extend: "pdfHtml5",
    customize: function(doc) {
      age = table.column(3).data().toArray();
      for (var i = 0; i < age.length; i++) {
        if (age[i] < 40) {
          doc.content[1].table.body[i+1][3].fillColor = 'blue';
        }
      }
    }
  }
]

Answer 2

doc.content[1].table.body[0].forEach(function (h) {
        h.fillColor = '#000';
        alignment: 'center'
    });
 
    doc.styles.title = {
        color: '#2D1D10',
        fontSize: '16',
        alignment: 'center'
    }
