Hi, I'm doing a bit of styling in TableView. The result is quite nice but I can't make the left top corner round.

This is the actual result:

And this is the css (happy to share it)

.table-view {
    -fx-background-color: transparent;    
}

/*HEADER */
.table-view .column-header{       
    -fx-background-color: #27A5F9;    
    -fx-size: 45.0px;
    -fx-min-height: 45.0px;    
    -fx-cursor: hand;
}


.table-view .column-header .label {
    -fx-font-size: 1.083333em;
    -fx-font-weight: bold;    
    -fx-text-fill: white;
    -fx-alignment: center-left; 
    -fx-padding: 5.0 5.0 5.0 5.0;
}


.table-view .filler{
    -fx-background-radius: 0.0 5.0 0.0 0.0;  
    -fx-background-color: #27A5F9;    
    -fx-size: 45.0px;
    -fx-min-height: 45.0px;    
}

.table-view .show-hide-columns-button{
    -fx-background-color: #27A5F9;    
}

.table-view .column-drag-header{
    -fx-background-color: #27A5F9;
    -fx-cursor: h-resize;
}

.table-view .column-resize-line{
    -fx-text-fill: white;
    -fx-background-color: white;
    -fx-fill: white;
    -fx-border-color: white;
    -fx-border-width: 1;
}

.table-view .column-header .sort-order{
    -fx-text-fill: white;
    -fx-fill: white;
}


.table-view .placeholder{
     -fx-background-color: white;    
}

.table-view .placeholder .label {
    -fx-font-size: 1.1em;
    -fx-font-weight: bold;    
    -fx-text-fill: #27A5F9;
    -fx-alignment: center; 
}


.table-view .virtualflow{
    -fx-background-color: white;
}

/* Each row in the table is a table-row-cell. Inside a table-row-cell is any
   number of table-cell. */
.table-row-cell {
    -fx-background-color: transparent;   
    -fx-border-width: 0.0;
    -fx-padding: 10.0 0.0 10.0 0.0;    
    -fx-pref-height: 45.0px;  
}


.table-row-cell:filled:even{
    -fx-background-color: white;
}


.table-row-cell:filled:odd{
    -fx-background-color: #F6F7F8;
}


.table-view:row-selection .table-row-cell:filled:hover {
    /*-fx-background-color: red;*/
}
.table-view:row-selection .table-row-cell:filled:hover .text{
    /*-fx-fill: white;*/       
}


.table-row-cell:filled:focused {
    -fx-background-color: #e1e2e3;           
    -fx-background-insets: 0.0;
}


.table-row-cell:filled:focused .text{    
}


.table-row-cell .table-column{
    -fx-border-width: 0.0;    
    -fx-padding: 0.0 0.0 0.0 5.0;     
}

/*TESTO DELLE CELLE */
.table-row-cell .text{
    -fx-font-size: 1.1em;
    -fx-fill: #6F7B8A;
}

/*SCROLL BAR VERTICALE */
.table-view .scroll-bar:vertical{        
    -fx-padding: 0.0 0.0 0.0 0.0;
}

/*SCROLL BAR ORIZZONTALE */
.table-view .scroll-bar:horizontal {
    -fx-padding: 0.0 0.0 0.0 0.0;
}

I would also like the top left corner was round.

Thanks
