QTable - functions for setting row style / classes (table-row-style / table-row-class)

[aleksander237]

Sometimes base on some criterias we want to set the TR style / class. The most common example would be coloring the whole row if a record has property set to certain value - let's say reddish background for erros in log viewer.

The functions could take props as a parameter. For instance:

<q-table :table-row-style-fn="tableRowStyleFn" :table-row-class-fn="tableRowClassFn">
</q-table>

and methods

methods: {
    tableRowStyleFn(props) {
        return props.row.level === 'ERROR' ? ' text-color: white' : '';
    },
    tableRowClassFn(props) {
        return props.row.level === 'ERROR' ? ' bg-red-1' : '';
    }
}

Currently I'm using the body slot, but it could be problematic espacially with dynamic column setup "wide" (multi columns) tables.

I think having a possibility to do this would be a great addition to the QTable.

Stumbled upon this issue while searching for a way to highlight a full row in a table based on some criteria. In our case, we’d like to highlight a task list based on the due date and / or status.

Since we have quite some custom <template v-slot:body-cell-name="props">, this would help a lot.

this is needed to apply styles conditionally, based on the row data

To highlight a row, can add function in cell classes props / style props:

const tableRowClassFn = row=> row.level === 'ERROR' ? ' text-red' : ''
const tableRowStyleFn = row=> row.level === 'ERROR' ? ' text-color: red' : ''

// Add in table columns obj:
const columns = [{
      name: 'A', label: 'A', classes: tableRowClassFn 
  },{
      name: 'B', label: 'B', style: tableRowStyleFn 
  }
}

@orzinc Thanks for the suggestion! I use this for styling as a fix currently, but it doesn't work if you have a selection column. And a feature for this is already implemented, hoping it'll get merged soon :)

It seems that card-class property must do the requied capability.
This property has the description in current docs:
CSS classes to apply to the card (when in grid mode) or container card (when not in grid mode)
And one of examples:
card-class="{ 'my-special-class': [Boolean condition] }"

But I don't understand what the [Boolean condition] can be. And how to use it, and can it be row-dependent.

@orzinc Your solution is good. But works only when all colums described in body-cell-[name] slots. For those colums, that not described in individual slot, the class specified in classes column property is not applyed to TD element.

New QTable props will be available in Quasar v2.18.0 -> table-row-style-fn, table-row-class-fn, grid-style-fn, grid-class-fn.
If used, they need to be assigned a Function of form: (row: Object) => string
