CSS TABLE表行HEIGHT ISSUE

Question

我在最后几个小时面临一个问题，我无法弄明白。我在php脚本中定义了一个html表，如下所示：

＆＃13;

＆＃13;

    /* 
	Generic Styling, for Desktops/Laptops 
	*/
	#table_products
	{
		display: block; 
	}
	table { 
		width: 100%; 
		height: 300px;
		max-height: 300px;
		border-collapse: collapse;
		overflow:auto;
		font-size:11px;		
	}
	table thead tr{
		height: 35px; max-height: 35px;
	}
	/* Zebra striping */
	tr:nth-of-type(odd) { 
		background: #eee;
	}
	
	th { 
		background: #333; 
		color: white; 
		font-weight: bold; 
	}
			
	td, th { 
		padding: 2px;
		border: 1px solid #ccc; 
		text-align: center; 
		white-space: -moz-pre-wrap !important;  /* Mozilla, since 1999 */
		white-space: -pre-wrap;      /* Opera 4-6 */
		white-space: -o-pre-wrap;    /* Opera 7 */
		white-space: pre-wrap;       /* css-3 */
		word-wrap: break-word;       /* Internet Explorer 5.5+ */
		white-space: -webkit-pre-wrap; /* Newer versions of Chrome/Safari*/
		word-break: break-all;
		white-space: normal;
		vertical-align: middle;
	}
	
@media 
	only screen and (max-width: 760px),
	(min-device-width: 768px) and (max-device-width: 1024px)  {
	
		/* Force table to not be like tables anymore */
		table, thead, tbody, th, td, tr { 
			display: block; 
		}
		
		th { 
		font-weight: bold; 
		vertical-align: middle;
			
	}
	
		/* Hide table headers (but not display: none;, for accessibility) */
		thead tr { 
			position: absolute;
			top: -9999px;
			left: -9999px;
		}
		
		tr { border: 1px solid #ccc; }
		
		td { 
			/* Behave  like a "row" */
			border: none;
			border-bottom: 1px solid #eee; 
			position: relative;
			padding-left: 50%; 
		}
		
		td:before { 
			/* Now like a table header */
			position: absolute;
			/* Top/left values mimic padding */
			top: 6px;
			left: 6px;
			width: 45%; 
			padding-right: 10px; 
			white-space: -moz-pre-wrap !important;  /* Mozilla, since 1999 */
			white-space: -pre-wrap;      /* Opera 4-6 */
			white-space: -o-pre-wrap;    /* Opera 7 */
			white-space: pre-wrap;       /* css-3 */
			word-wrap: break-word;       /* Internet Explorer 5.5+ */
			white-space: -webkit-pre-wrap; /* Newer versions of Chrome/Safari*/
			word-break: break-all;
			white-space: normal;

		}
		
		/*
		Label the data
		*/
		td:nth-of-type(1):before { content: "X"; }
		td:nth-of-type(2):before { content: "Προιόν"; }
		td:nth-of-type(3):before { content: "#"; }
		td:nth-of-type(4):before { content: "Τιμή+"; }
	}
	
	/* Smartphones (portrait and landscape) ----------- */
	@media only screen
	and (min-device-width : 320px)
	and (max-device-width : 480px) {
		body { 
			padding: 0; 
			margin: 0; 
			width: 320px; }
		}
	
	/* iPads (portrait and landscape) ----------- */
	@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) {
		body { 
			width: 495px; 
		}
	}

＆＃13;

 <div id="table_products">
														<table>
															<thead>
															<tr>
																<th style="width:7%">X</th>
																<th style="width:58%">Προιόν</th>
																<th style="width:15%">#</th>
																<th style="width:20%">Τιμή+</th>
															</tr>
															</thead>
															<tbody>
															<tr>
																<td>x</td>
																<td>Salata </td>
																<td>234</td>
																<td>22.5679</td>
															</tr>	
															</tbody>
															
														</table>
													</div>

＆＃13;

＆＃13;

＆＃13;

但是我无法正确获得每一行的高度。我在桌子上的两行都有50％的高度，并填满整个300px的桌子高度。我希望每行的高度仅为25像素，并忽略表格的高度。

感谢任何建议
