javascript - 在渲染时隐藏检查单元 - extjs 6.5.3 现代

Question

如果另一个值是，我试图隐藏checkcella 。但不幸的是，根据sencha 文档，只有当单元格类型是 Ext.grid.cell.Cell 的默认值时才会处理此配置。checkcolumncolumnnull

所以renderer配置的解决方案将不起作用。

例如：

{
        xtype: 'checkcolumn',
        dataIndex: 'isSomething',
        text: '',
        width: 30,
        menuDisabled: true,
        headerCheckbox: false,
        renderer: function(value, record) {
            var relatedValue = record.get('somethingElse');
            return relatedValue ? new Ext.grid.column.Check().renderer(value) : '';
        }
    }

有什么提示或技巧可以做到这一点？

Answer 1

您可以使用gridcell并且可以在内部gridcell使用checkbox来实现您的要求。

在这个FIDDLE中，我使用gridcelland创建了一个演示checkbox。我希望这将帮助/指导您实现您的要求。
