Problem adding <div> custom-header class to v-slot:header.name

Dashboard
1

Here is my header template

<template v-slot:header.livePrice>
    <div class="custom-header">Current Price</div>
</template>

here is the CSS

/* Style for the header */
.custom-header {
  color: #E0E1DD;
  font-weight: bold;
  padding: 10px;
}

here is how the browser is rendering it

<th class="v-data-table__td v-data-table-column--align-start v-data-table__th--sortable v-data-table__th" colspan="1" rowspan="1">
  <div class="v-data-table-header__content d-flex align-center">
    <span class="custom-header">Current Price</span>
    <i class="mdi-arrow-up mdi v-icon notranslate v-theme--nrdb v-icon--size-default v-data-table-header__sort-icon" aria-hidden="true"></i>
  </div>
</th>

Any idea why my custom header is on the <span tag instead of <div tag?

This template is the same

<template v-slot:header.liveProfit>
  <div class="v-data-table-header__content">Profit</div>
</template>

I have a v-chip on that and doesn't work at all

<template v-slot:item.liveProfit="{ item }">
    <v-chip :color="getChipColor(item.liveProfit)">
        {{ item.liveProfit }} %
    </v-chip>
</template>

here is the script part

<script>
export default {
  data() {
    return {
      search: '', // Search query
      headers: [
	{ title: 'Current Price', key: 'livePrice' },
	{ title: 'Current Profit', key: 'liveProfit' },
      ]
    };
  },
  props: {
    msg: {
      type: Object,
      required: true
    }
  },
  methods: {
    // Determine the color of the profit chip based on profit value
    getChipColor(item.liveProfit) {
      if (item !== undefined) {
        if (item.liveProfit > 0) {
          return 'green';  // Profit is positive
        } else if (item.liveProfit < 0) {
          return 'red';    // Profit is negative
        } else {
          return 'orange'; // Profit is neutral
        }
      }
    }
  }
};
</script>

You are giving us snippets of code that dont make a lot of sense by themselves.

For example, pulling some of the parts together, i can get v-chips to display...

<template>
  <div v-for="item in items">
    <v-chip :color="getChipColor(item)">
        {{ item.liveProfit }} %
    </v-chip>
  </div>
</template>

<script>
export default {
  data() {
    return {
      search: '', // Search query
      headers: [
        { title: 'Current Price', key: 'livePrice' },
        { title: 'Current Profit', key: 'liveProfit' },
      ],
      items: [
        {liveProfit: 1.5},
        {liveProfit: -1.5},
        {liveProfit: 0},
      ]
    };
  },
  methods: {
    // Determine the color of the profit chip based on profit value
    getChipColor(item) {
      if (item !== undefined) {
        if (item.liveProfit > 0) {
          return 'green';  // Profit is positive
        } else if (item.liveProfit < 0) {
          return 'red';    // Profit is negative
        } else {
          return 'orange'; // Profit is neutral
        }
      }
    }
  }
};
</script>

Perhaps if you share a minimal flow, with sample data, we can help further.

That's more then enough for the chips I know where is the problem. The function should send the array data as numbers not as a string

But why the headers are rendered it as default class instead of using my custom class? some of the other columns have the same template with div class and they are OK

Here is the template I don't understand why this is not working. I use the same template for other data and I do not have problem

<template>
  <div>
    <v-card flat>
			<v-card-title class="d-flex align-center pe-2">
				<v-icon icon="mdi-check"></v-icon> &nbsp;
				Pending Trades ({{ msg?.payload[0]?.tradeCount || 0 }})

				<v-spacer></v-spacer>

				<v-text-field
					v-model="search"
					density="compact"
					label="Search"
					prepend-inner-icon="mdi-magnify"
					variant="solo-filled"
					flat
					hide-details
					single-line
				></v-text-field>
			</v-card-title>
		</v-card>
    <!-- Data Table -->
    <v-data-table 
			class="custom-table-background"
      v-model:search="search" 
      :items="msg?.payload" 
      :headers="headers">
      
      <!-- Custom header for Trade# column -->
      <template v-slot:header.trade>
        <div class="custom-header">Trade#</div>

      <!-- Custom header for Pair column -->
      <template v-slot:header.pair>
        <div class="custom-header">Pair</div>

      <!-- Custom header for Direction column -->
      <template v-slot:header.direction>
