Crosstab Dimension Heading Change via CSS Lumira designer 2.3

Hey Guys,

Need your help regarding Crosstab Dimension heading /Title change using CSS on Lumira designer 2.3.

Right now i am able to change measure column title using below CSS. Could you please point me to the right CSS code . Thank you.

.sapzencrosstab-ColumnHeaderArea>tbody>tr>td:nth-child(1):Before {
content: "Link";
} .sapzencrosstab-ColumnHeaderArea>tbody>tr>td:nth-child(1)>div {
visibility: hidden !important;
height: 0px !important;
}

.sapzencrosstab-DimensionHeaderArea>tbody>tr>td:nth-child(1):after {
content: "Link";
}
.sapzencrosstab-DimensionHeaderArea>tbody>tr>td:nth-child(1)>div {
