数据表隐藏/显示列

Question

我正在使用数据表来实现一些漂亮的功能，在这里我正在使用数据表来修复表的列

表结构

• 我正在用JSON数据创建表，该数据使用Java脚本是纯动态的
• 在表格上方，我有一个下拉字段，用户可以选择该字段，然后单击“转到”，而我仅显示该用户正在选择的列
• 用户选择1或2列，然后选择tbody和thead are breaking列
• 当我删除fixedColumn时，它工作正常，但我需要实现fixedColumn
• 当我选择下拉菜单并按go时，我固定的列也会显示两次。

工作代码

function format(number, decimals = 2, locale = 'en-in') {
  const fixed = parseInt(number).toFixed(decimals);
  const [int, dec] = fixed.split('.')
  const intFormatted = (+int).toLocaleString(locale)
  return intFormatted + (dec ? '.' + dec : '');
}

var data = [{

编辑/更新

我现在正在使用数据表，但是，就像使用data-columnindex一样，但是它只隐藏第一列数据，就像我gros amount，Discount，Gst一样， Net Amount在billdate以外的每一列中都很常见，所以我要尝试的是单击Net Amount时所有净额列都应隐藏

我认为可以使用数据表来完成，而无需更改我的Java脚本
外面有人请帮帮我

Answer 1

我认为您需要隐藏列值。它的两个班轮代码。您可以分两步完成。

1-全局声明表变量。

var table;

现在为其分配数据表对象。

table =$(table).DataTable({ //adding datatabl functionality 
    "scrollX": true,
    "scrollY": $bodyHeight + "px",
    "scrollCollapse": true,
    "paging": false,
    "info": false,
    "ordering": false,
    "searching": false,
    fixedColumns: {
      leftColumns: 1
    }
  });

现在您有了可以使用它的桌子对象。

$("#save").on("click", function() {

   // Get the column API object
    var column = table.column( $(this).attr('data-column') );
    // Toggle the visibility
    column.visible( ! column.visible() );
});
