Table Row Height Intermittent

Is it possible to paste the html and css here and I can have a look?

Absolutely...

**CSS**

Code:

table.item-table{width:100%;border-collapse:collapse;border-spacing:0;margin-bottom:10px;font-size:12px}

table.item-table tr:nth-child(2n-1) td{background:#F5F5F5}

table.item-table th{padding:5px 0;border-bottom:1px solid #606060;white-space:nowrap;text-align:left}

table.item-table th.text-right{text-align:right}

table.item-table th.text-center{text-align:center}

table.item-table td{padding:5px 0}

table.item-table .invoice-sums{text-align:right;}
