Keep in mind that vue dispatches the style/class prop to the parent element of your component.
So the following should work:
<el-button style="width: 100%">Default</el-button>

You can make it by adding a full-width column in it,
like so.
<el-row>
<el-col :span="24">
<el-button type="primary"> Your Button Here </el-button>
</el-col>
</el-row>
