vaadin - 更改网格中单元格的颜色(Vaadin)

Question

我在 Grid 中使用 BeanItemContainer 来显示我的数据。我需要根据单元格中的数据分别为每个单元格着色。

Answer 1

section about the Grid在 Vaadin 的书中，在 Generating Cell Styles 小节中解释了这一点:

You set a CellStyleGenerator to a grid with setCellStyleGenerator(). The getStyle() method gets a CellReference, which contains various information about the cell and a reference to the grid, and should return a style name or null if no style is generated.

For example, to add a style name to a specific column, you can match on the property ID of the column as follows:

grid.setCellStyleGenerator(cellRef -> // Java 8
    "born".equals(cellRef.getPropertyId())?
        "rightalign" : null);

You could then style the cells with a CSS rule as follows:

.v-grid-cell.rightalign {
    text-align: right;
}
