[SalesForce] Hide button inside Lightning Datatable based on row value

See this link: Componente Library-Datatabel

Look for "Column Properties" in this page and editable property. Set this property to true.

Or see this sample : enter link description here

You can use lightning components in your visualpage, check this.: enter link description here

for hardcode sample that do you want, many code is necessary to make this and many javascript.

When you define a datatable you asign an error attribute to it.

Now whenever you feel that you should display error for a particular cell after a validation session, you just input values to the errors attribute.

Define the errors and map them to fieldNames. When the error is triggered, the borders for the amount and contact cells turn red to represent the error state.

<lightning:datatable keyField="id" data="{! v.mydata }" columns="{! v.mycolumns }"
    errors="{!v.errors}"/>

JS Code:

validateValues : function(component , event ,helper){

    //Run your validate logic

    cmp.set('v.errors', {
                rows: {
                    b: {
                        title: 'We found 2 errors.',
                        messages: [
                            'Enter a valid amount.',
                            'Verify the email address and try again.'
                        ],
                        fieldNames: ['amount', 'contact']
                    }
                },
                table: {
                    title: 'Your entry cannot be saved. Fix the errors and try again.',
                    messages: [
                        'Row 2 amount must be number',
                        'Row 2 email is invalid'
                    ]
                }
            });

}
