As of my knowledge cutoff date in September 2021, the filter-method attribute in the q-table component of Quasar Framework works well with TypeScript.

In Quasar, the q-table component allows you to customize how the data is filtered by providing a filter-method attribute. This attribute allows you to define a custom filtering function that will be used to filter the data displayed in the table based on specific criteria.

When using TypeScript with Quasar, you can define the filter-method function in a type-safe manner. TypeScript will provide type checking and autocompletion support to help you ensure that the function is correctly typed and compatible with the filter-method attribute.

Here's an example of how you can use filter-method with TypeScript in Quasar:

<template> <q-table :rows="tableData" :columns="tableColumns" :filter-method="customFilterMethod" /> </template> <script lang="ts"> import { defineComponent } from 'vue'; export default defineComponent({ data() { return { tableData: [ { name: 'John', age: 30 }, { name: 'Jane', age: 25 }, // Add more data rows as needed ], tableColumns: [ { name: 'name', required: true, label: 'Name', align: 'left', field: 'name' }, { name: 'age', required: true, label: 'Age', align: 'left', field: 'age' }, // Add more columns as needed ], }; }, methods: { customFilterMethod(rows: any[], terms: string, cols: any[]) { // Your custom filtering logic here // For example, you can filter based on the 'name' field return rows.filter((row) =>; }, }, }); </script>

In this example, we have defined a customFilterMethod function in the component options, and TypeScript provides type checking for the parameters (rows, terms, cols) and the return value of the function.

Keep in mind that the specific implementation of the customFilterMethod function will depend on your data structure and the filtering logic you want to apply. TypeScript ensures that the function adheres to the expected types and helps you avoid type-related errors.

Please note that the state of Quasar and its TypeScript integration might change after my knowledge cutoff date. It's always a good idea to refer to the official Quasar documentation and TypeScript definitions for the most up-to-date information and best practices.
