Tips for updating the background color of a specific row

I have a piece of code that I am trying to modify with a specific condition. If {row.BB} is less than or equal to 100, I want to change the background color of the row with this value to red. Can someone help me achieve this? The code is linked to a database and uses a JSX file.

    return (
        <>
            <Navigation />
            <Box bg={'white'} w="100%"
                 p={4}
                 m={4}
                 color="black"
                 rounded={'md'}
            >
                     <Table size='sm' variant='striped' colorScheme='gray'>
                         <Thead>
                             <Tr>
                                <Th>A</Th>
                                <Th>B</Th>
                                <Th>C</Th>
                             </Tr>
                         </Thead>
                         <Tbody>
                         {file.map((row, index) => (
                             <Tr key={index}> 
                                 <Td>{row.AA}</Td>
                                 <Td>{row.BB}</Td>
                                 <Td>{row.CC}</Td>
                             </Tr>
                         ))}
                         </Tbody>
                     </Table>
            </Box>
        </>
    );

Answer №1

It seems like the 'bg' attribute is being used to set the background color of each row, which is also utilized for the Box component's background color in your code.

<Tr bg={ () => this.getColorOftheRow(row.BB) } key={index}> 
    <Td>{row.AA}</Td>
    <Td>{row.BB}</Td>
    <Td>{row.CC}</Td>
</Tr>

within the component

function getColorOftheRow(value) {
            if (value <= 100)
                return 'red';
            else if (value >= 100)
                return 'green';
                // add more conditions if needed
            else
                return 'white';
        }

It seems like your question is a bit unclear, but if you are looking to modify this specific row <Td>{row.BB}</Td>, there are two approaches you can take:

Utilizing an If-Else block

` {file.map((row, index) => (

if (row.BB <= 100){
    return (
        <Tr key={index} style={{backgroundColor:'red'}}> 
            <Td>{row.AA}</Td>
            <Td>{row.BB}</Td>
            <Td>{row.CC}</Td>
        </Tr>
    )
else {
    return(
        <Tr key={index}> 
            <Td>{row.AA}</Td>
            <Td>{row.BB}</Td>
            <Td>{row.CC}</Td>
        </Tr>
    )}
}
))}

`

If you are familiar with the ternary operator, you can simplify the process: ` { file.map((row, index) => (

 { row.BB <= 100 ? 
 (<Tr key={index} style={{ backgroundColor: 'red' }}> 
     <Td>{row.AA}</Td>
     <Td>{row.BB}</Td>
     <Td>{row.CC}</Td>
 </Tr>)
 : 
 (<Tr key={index}> 
     <Td>{row.AA}</Td>
     <Td>{row.BB}</Td>
     <Td>{row.CC}</Td>
 </Tr>)
 }

))}} `

If any of these methods do not work for you, please inform me.

 }

There are various approaches you could take to tackle this issue, but I believe the most straightforward method would be to keep it uncomplicated (especially since you are already utilizing traditional <table> and <td> elements).

You might want to consider implementing something along these lines:

<Tr>
  ...
  <Td bgcolor={row.BB <= 100 && 'red'}></Td>
</Tr>

Please let me know if that suggestion proves effective for your needs.
