Summary
The lightning:datatable minColumnWidth and maxColumnWidth attributes are not working as documented. The specified widths are ignored

Repro
1. Create the following Lightning Component:

Component
-----------------------------------
<aura:component implements="aura:requireLocker">
<aura:attribute name="mydata" type="Object"/>
<aura:attribute name="mycolumns" type="List"/>
<aura:handler name="init" value="{!this}" action="{!c.init}"/>
<lightning:datatable
data="{!v.mydata}"
columns="{!v.mycolumns}"
keyField="Id"
maxColumnWidth="350"
minColumnWidth="300"
resizeStep="20"
/>
</aura:component>
-----------------------------------

Controller
-----------------------------------
({
init: function (cmp) {
cmp.set('v.mycolumns', [
{label: 'Contact Name', sortable: true, fieldName: 'Name', type: 'text' },
{label: 'Phone', fieldName: 'Phone', type: 'phone' }
]);

cmp.set('v.mydata', [
{ Id: 1, Name: 'John', Phone: '415-982-1234'},
{ Id: 2, Name: 'Jane', Phone: '415-123-2133'}
]);
}
})
-----------------------------------

2. Resize the table columns. Observe that the max (350) and min (300) widths are not applied. The columns are resizable to a minimum of 50px and a maximum of 1000px which are the default values
