blockRendering.RenderInfo.getElemCenterline_() 方法
在算繪的列中計算元素的中心線。這項基本實作會在資料列中間垂直放置中心線,沒有特殊案例。您可能需要額外的邏輯來處理頂端和底部資料列。

It positions the centerline at the row's vertical midpoint. The method takes a `Row` and a `Measurable` element as input. It returns a number representing the element's centerline offset from the block's top-left corner. Custom implementations are often needed to adjust positioning for specific rows.\n"]]
