Change scoped field slots name syntax

Due to new Dynamic Arguments feature of Vue when we want to define new field slot in table, should add two \ to field name : e.g

<template #\[field_name\]="row">Some thing...</template>

I think field slots name syntax can be better, something like __field_name or _field_name_.

When used in document DOM templates there can be issues with \. But not when using Vue-loader

Note that \ are not allowed in attribute names.

You got it wrong, I don’t using \ as attribute name, just escaping [ & ] in attribute name and Vue allow this.
