我有以下代码，我想根据 if 语句隐藏或显示 TableCell，我该怎么做？
我正在使用 MATERIAL-UI:https://material-ui.com/
<TableBody>
{Object.entries(servicesCode).map(([key, value]) => (
servicesValueTotal[key] = ((servicesValue[key] + servicesTaxe[key])),
<TableRow key={servicesCode[key]}>
<TableCell component="th" scope="row">
{key}
</TableCell>
<TableCell align="center" >{servicesCode[key]}</TableCell>
<TableCell align="center">{servicesValue[key]}</TableCell>
<TableCell align="center">{servicesTaxe[key]}</TableCell>
<TableCell align="center">{servicesValueTotal[key]}</TableCell>
<TableCell align="center">{servicesTec[key]}</TableCell>
<TableCell align="center">{servicesClient[key]}</TableCell>
<TableCell align="center">{servicesStatus[key]}</TableCell>
</TableRow>
))}
</TableBody>
最佳答案
let showTableCell = (true) ? true : false; // you can have a single line condition or multiple line condition using if and else here.
<TableBody>
{Object.entries(servicesCode).map(([key, value]) => (
servicesValueTotal[key] = ((servicesValue[key] + servicesTaxe[key])),
<TableRow key={servicesCode[key]}>
<TableCell component="th" scope="row">
{key}
</TableCell>
{showTableCell && <TableCell align="center" >{servicesCode[key]}</TableCell>}
// or you could also add condition here as well
{showTableCell ? <TableCell align="center">{servicesValue[key]}</TableCell> : "Some other data here"}
<TableCell align="center">{servicesTaxe[key]}</TableCell>
<TableCell align="center">{servicesValueTotal[key]}</TableCell>
<TableCell align="center">{servicesTec[key]}</TableCell>
<TableCell align="center">{servicesClient[key]}</TableCell>
<TableCell align="center">{servicesStatus[key]}</TableCell>
</TableRow>
))}
</TableBody>
