Hi everyone,

I am using a Lightning Data table component that i can access from my desktop or my Salesforce mobile App.
It is built like this : 
 

<lightning:datatable aura:id="WSTable" data="{!v.filteredData}" class="slds-m-top_medium"
                columns="{!v.columns}"
                minColumnWidth="100px"
                keyField="identsrc"                             
                onrowselection="{!c.getSelectedRow}"
                sortedBy="{!v.sortedBy}"
                sortedDirection="{!v.sortedDirection}" 
                maxRowSelection = "1"
                onsort = "{!c.updateColumnSorting}"/>	           
    </lightning:card>

In desktop mode, the Data table is well displayed ! However, when i am in my app, it is displayed like this :


So it is totally unreadable, and i would like to know how to fix this. I already tried to set a minWidth for the colums but it doesn't work.

Thanks in advance !
