How to override CSS style during hover in a table row? - css

Question

I saw several questions on this forum related to my problem but neither of them were helpful, so am posting here.
I have a table where a style is applied at table level(.tblSignal) and td level (.tdSignalName). Here is jsfiddler link
My problem is, when I hover on the table, all the text should turn to white color. But since there is a style applied on .tdSignalName as "#0072c6", it does not override the color to white. I tried "!important" but it did not work. Please advise !
.tblSignal{
/* border-width:1px; */
border-style:solid;
}
.tblSignal:hover{
background-color:#0072c6;
color:#FFFFFF !important;
font-size:initial;
}
.tdSignalName{
font-weight:bold;
height:30px;
font-size:16px;
color:#0072c6;
}
/* .tdSignalName:hover{
color:#FFFFFF !important;
} */
.tdSignalDescription{
}
.tdSigButton{
text-align:center;
vertical-align:middle;
}
<table class="tblSignal" width="500px">
<tr >
<td class="tdSignalName" width="400px">
<div>Title</div>
</td>
<td rowspan="2" class="tdSigButton" width="100px">
<div id="divButton">
<button id="btnReport" onclick="window.open('_#=SignalReportURL=#_')">Run Report</button>
</div>
</td>
</tr>
<tr>
<td class="tdSignalDescription" width="400px">
<!-- _#=ctx.RenderBody(ctx)=#_ -->
<div><i>SignalDescription </i></div>
</td>
</tr>
</table>

You need to also override the .tdSignalName colour declaration when the parent is hovered...
.tblSignal:hover .tdSignalName {
color:#FFFFFF;
}
Example...
.tblSignal {
border-style: solid;
}
.tblSignal:hover {
background-color: #0072c6;
color: #FFFFFF !important;
font-size: initial;
}
.tdSignalName {
font-weight: bold;
height: 30px;
font-size: 16px;
color: #0072c6;
}
.tblSignal:hover .tdSignalName {
color: #FFFFFF;
}
.tdSigButton {
text-align: center;
vertical-align: middle;
}
<table class="tblSignal" width="500px">
<tr>
<td class="tdSignalName" width="400px">
<div>Title</div>
</td>
<td rowspan="2" class="tdSigButton" width="100px">
<div id="divButton">
<button id="btnReport" onclick="window.open('_#=SignalReportURL=#_')">Run Report</button>
</div>
</td>
</tr>
<tr>
<td class="tdSignalDescription" width="400px">
<!-- _#=ctx.RenderBody(ctx)=#_ -->
<div><i>SignalDescription </i></div>
</td>
</tr>
