如何在 handsontable 中格式化列标题？

我有一个 jsfiddle展示我到目前为止所拥有的。我可以格式化第一行数据，将列标题更改为我的标题，但我似乎无法格式化列标题。

var secondData = [
  ["2008", -0.5, 2, 2.2, -7],
  ["2009", -0.1, 3, 4.2, -2.6],
  ["2010", 3, 2, -1, 1]
];

var secondHeader = [
  {title: "Year", type: 'text'},
  {title: "Kia", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "Nissan", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "Toyota", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "Honda", type: 'numeric', format: '0.0%', renderer: percentRenderer}
];

$("#headerGrid").handsontable({
  data: secondData,
  columns: secondHeader,
  minSpareCols: 0,
  minSpareRows: 0,
  rowHeaders: false,
  colHeaders: true,
  contextMenu: true,
  cells: function (row, col, prop) {
    var cellProperties = {};
    if (row === 0) {
      cellProperties.renderer = firstRowRenderer; 
    }
    return cellProperties;
  }
});

function percentRenderer (instance, td, row, col, prop, value, cellProperties) {
  Handsontable.renderers.NumericRenderer.apply(this, arguments);
  td.style.color = (value < 0) ? 'red' : 'green';
};

function firstRowRenderer(instance, td, row, col, prop, value, cellProperties) {
  Handsontable.renderers.TextRenderer.apply(this, arguments);
  td.style.fontWeight = 'bold';
  td.style.color = 'green';
  td.style.background = '#CEC';
}

第三个选项是 Handsontable 有它自己的 th CSS，您需要为单元格格式覆盖它。如果您想要更改单个标题，您可以像这样修改 CSS:

.handsontable th:nth-child(1){
    background-color:aquamarine;
    font-weight:bold;
}

columns 属性还在标题中采用 HTML，因此您可以添加 span 并在 CSS 中设置文本(但不是单元格)的样式。

var secondHeader = [
  {title: "Year", type: 'text'},
  {title: "Kia", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "<span class='headerBold'>Nissan</span>", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "Toyota", type: 'numeric', format: '0.0%', renderer: percentRenderer},
  {title: "Honda", type: 'numeric', format: '0.0%', renderer: percentRenderer}

];

span.headerBold{
    font-weight:bold;
}
