As in the following example, you can express a table in a formula by using theTablefunction with a set of records, which you express in curly braces: Table( { Value: "Strawberry" }, { Value: "Vanilla" } ) You can also define a single-column table with square brackets. An equivalent...
Delegation warnings help you manage your app so that it has correct results. If the data in your data source exceeds 500 records and a function can't be delegated, Power Fx will mark the formula with a blue underline. Delegable data sources ...

这里主要讲解 Konva 和飞书 Bitable 里面的离屏渲染。 在Konva 中的离屏渲染主要是针对 Group 级别来做的,通过调用 cache 方法就能实现离屏渲染。基于Group 来做离屏渲染的原理是: 调用cache 方法,创建一个离屏 Canvas 节点。 遍历Group 子节点进行绘制,同时将其绘制到离屏 Canvas 上面。 下次batchDraw 的时候判断...
