Question

我正在编码一个交易表，该交易表应以红色显示借方值，以绿色显示贷方值，但是我希望这种颜色仅在使用javascript的表数据大于0时才生效。请帮助...

df = pd.DataFrame( { 'category': ['Cosmetics', 'Fruits', 'Clothes'],
                     'value': [789.99,27.68, 179.20],
                    'percentage_difference': [300.0,400.0,500.0]})
df['merge_value'] = df.apply(lambda r: "{0}({1}, {2}%)".format(r['category'], r['value'], r['percentage_difference']), axis=1)

通过查看html，看来您正在使用数据表，因此您必须使用jQuery，这就是我的处理方法。

$(document).ready(function() {
  var table = $('#example').DataTable({
    columnDefs: [{
      targets: 3,
      render: function(data, type, row) {
        var color = 'black';
        if (data < 0) {
          color = 'red';
        }
        if (data > 0) {
          color = 'green';
        }
        return '<span style="color:' + color + '">' + data + '</span>';
      }
    }]
  });
});
