根据 if 条件添加额外的 defaulContent 列

Question

下午好，我已经用从 wcf 服务检索的数据填充了一个数据表（jQuery 的表插件），它有一个列 defaultContent，它有一个链接并且效果很好，但现在我需要创建一个额外的 defaultContent 列和另一个链接取决于 if 条件，如下所示

if (tipo_evento == 3213) { ... add a defaultContent...}

我已经尝试将 if 添加到下面的代码中，但这是不可能的，你能告诉我如何添加额外的列吗？这是我表的代码

function cargarTabla() {
            $('#myTable').DataTable({
                searching: false,
                paging: false,
                responsive: true,
                ordering: false,
                bInfo: true,
                bLengthChange: false,
                processing: true,
                info: true,
                deferRender: true,
                orderMulti: false,
                bAutoWidth: false,
                "ajax": {
                    "url": "/Home/CargarTabla?id=" + noDocumento + "&grupo=" + grupoDT,
                    "type": "GET",
                    "datatype": "json"
                },

                        { "data": "apellidos", "autoWidth": false, "orderable": false, "sClass": "alignRight", "sWidth": "18%" },
                        { "data": "dui", "autoWidth": false, "orderable": false, "sClass": "alignRight", "sWidth": "5%" },
                        { "data": "numero_isss", "autoWidth": false, "orderable": false, "sClass": "alignRight", "sWidth": "5%" },
                        { "data": "cargo_participante", "autoWidth": false, "orderable": false, "sClass": "alignRight", "sWidth": "20%" },

                        { "data": "nivel_puesto", "autoWidth": false, "orderable": false, "visible": false },
                        { "data": "grupo", "autoWidth": false, "orderable": false, "visible": false },
                        { "defaultContent": " <a href='#' id='select'>Sustituir</a>  ", "autoWidth": true, "orderable": false, "sClass": "alignRight", "sWidth": "5%" }
                ],
                "oLanguage": {
                    "sEmptyTable": "No hay registros disponibles",
                    "sInfo": " _TOTAL_ registros. Mostrando de (_START_ a _END_)",
                    "sLoadingRecords": "Por favor espera - Cargando...",
                    "sSearch": "Filtro:",
                    "sLengthMenu": "Mostrar _MENU_",
                    "oPaginate": {
                        "sLast": "Última página",
                        "sFirst": "Primera",
                        "sNext": "Siguiente",
                        "sPrevious": "Anterior"
                    },
                    "oAria": {
                        "sSortAscending": ": Activar para ordenar la columna de manera ascendente",
                        "sSortDescending": ": Activar para ordenar la columna de manera descendente"
                    }
                }
            });
        }

我刚刚从 Gyrocode.com 添加了这段代码，它工作得很好，但是刚刚添加的列在我的表中占用了太多空间，如何添加“autoWidth”：true，“orderable”：false，“sClass”： "alignRight", "sWidth": "5%" ?

"render": function (data, type, full, meta) {
                                if (type === 'display') {
                                    if (tipo_evento == 3213) {
                                        data = " <a href='#' id='Teliminar'>Eliminar</a> " +"|"+ " <a href='#' id='select'>Sustituir</a> ";
                                    } else {
                                        data = " <a href='#' id='select'>Sustituir</a> ";
                                    }
                                }
                                return data;

Answer 1

使用columns.render 选项为单元格生成内容。

例如，根据tipo_evento变量的值生成内容：

{ 
    "render": function(data, type, full, meta){
       if(type === 'display'){
          if(tipo_evento == 3213){
             data = "";
          } else {
             data = " <a href='#' id='select'>Sustituir</a> ";
          }
       }

       return data;
    },
    // ... other options ...
    "autoWidth": true, 
    "orderable": false, 
    "sClass": "alignRight", 
    "sWidth": "5%" 
}
