Grid custom no field

[abangkis]

Hi, when adding a custom no field to my grid, to show the no of the actual
row, i declared an int on the page and calculate the value by multiplying
the variables in the grid like the code bellow.

Is there a way to do this automatically, since for now i'm doing it
manually by copy and pasting the code to every page that uses grid.

Thank you verymuch

<table t:id="grid" t:type="grid" t:source="loans" t:row="loan"
rowIndex="idx" t:inPlace="true"
       t:add="no">
    <p:noCell>
        ${idx}
    </p:noCell>
</table>

@InjectComponent
private Grid grid;

private int idx;


public void setIdx(int idx) {
    this.idx = idx;
}

public int getIdx() {
    return grid.getRowsPerPage() * (grid.getCurrentPage() - 1) + idx + 1;
}
