如何删除jqgrid中的水平线(how to remove horizontal lines in jqgrid)

 我该如何做到这一点？ 
 
 HTML 
 
<table id="myGrid"><table>


//in my js I make it into a jqgrid

//css
.ui-jqgrid tr.ui-row-ltr td { border: none;}
.ui-jqgrid tr.ui-row-ltr td { border-collapse:collapse}
 
 垂直线消失，但水平线保留。 
 
 请不要让我看一个不同的答案，因为建议不起作用，这就是我发布的原因 - 我需要删除行。 

How do I achieve doing that?
 
html
 
<table id="myGrid"><table>


//in my js I make it into a jqgrid

//css
.ui-jqgrid tr.ui-row-ltr td { border: none;}
.ui-jqgrid tr.ui-row-ltr td { border-collapse:collapse}
 
The vertical lines are gone but the horizontal ones remain.
 
Please do not offer me to look at a different answer as the suggestions did not work which is why I am posting - I need the lines removed.
