使用Javascript根据单元格值设置材质UI表格单元格背景颜色?
这可能是一个基本的问题,但我不能绕着它转。我正在使用React和JS,希望根据单元格的值更改“Charge Left”单元格的背景。例如,如果电荷<30,背景为红色,如果电荷为31-59,背景为橙色,如果电荷>59,背景为绿色 我在JSAN中尝试了多种不同的解决方案,但我根本无法让它工作使用Javascript根据单元格值设置材质UI表格单元格背景颜色?,javascript,css,reactjs,material-ui,react-table,Javascript,Css,Reactjs,Material Ui,React Table,这可能是一个基本的问题,但我不能绕着它转。我正在使用React和JS,希望根据单元格的值更改“Charge Left”单元格的背景。例如,如果电荷59,背景为绿色 我在JSAN中尝试了多种不同的解决方案,但我根本无法让它工作 {user.chargeLeft} import React,{useffect,useState}来自“React”; 导入“/App.css”; 导入“/colorChange.jsx”; 从“aws Amplify”导入Amplify,{API,graphqlOper

我为StyledTableCell创建了一个新文件并定义了样式。请注意,您可以在makeStyles中使用道具来更改依赖于道具的样式
此外,还可以通过类属性将根类传递给TableCell
从“React”导入React;
从“@material ui/core/styles”导入{makeStyles}”;
从“@material ui/core/TableCell”导入TableCell;
const useStyles=makeStyles((主题)=>({
根目录:{
背景:(道具)=>{
如果(道具费用=31和道具费用5
返回“绿色”;
}
},
},
}));
const StyledTableCell=(道具)=>{
常量类=使用样式2(道具);
返回(
{props.children}
);
};
导出默认样式表单元格;
然后,在主文件中,将电荷道具传递给新组件:
