@Njir It might be a problem of material-ui library

<TableHeaderColumn key="login" tooltip="User ID">ID</TableHeaderColumn>
<TableHeaderColumn key="following" tooltip="The following" style={{width: '80px', }}>Following</TableHeaderColumn>
<TableHeaderColumn key="followers" tooltip="The followers" style={{width: '80px', }}>Followers</TableHeaderColumn>
<TableHeaderColumn key="updated_at" tooltip="Updated Date" style={{width: '150px', }}>Updated Date</TableHeaderColumn>
<TableHeaderColumn key="url" tooltip="oh-my-github URL">oh-my-github URL</TableHeaderColumn>

I guess that some columns have the style that fixed width like above code.
So the ID column's data shrinks on small device.
But it has not yet been tested.
