直接在table標籤中設置下不就行了嗎？這是靜態的，如果要動態設置你會嗎？
function com_onresize(){var contentsHeight = document.body.clientHeight;var buttonsHeight = document.getElementById( "buttons" ).offsetHeight;var head1Height = document.getElementById( "head1" ).offsetHeight;var head2Height = document.getElementById( "head2" ).offsetHeight;var t1 = document.getElementById( "TableContainer1" ).style.height;var t2 = document.getElementById( "TableContainer2" ).style.height;//alert(document.getElementById( "TableContainer1" ).style.height);var h = contentsHeight - buttonsHeight - head1Height - head2Height - 13;if(h < 110){return;}document.getElementById( "TableContainer1" ).style.height = h/2 + 'px';document.getElementById( "TableContainer2" ).style.height = h/2 + 'px';}function com_sbs_pagesize(){var screenHeight = window.screen.height; var availHeight = window.screen.availHeight; //alert(document.getElementById( "TableContainer1" ).children[0].rows.length); var index = document.getElementById( "TableContainer1" ).children[0].rows.length var buttonsHeight = document.getElementById( "buttons" ).offsetHeight;var head1Height = document.getElementById( "head1" ).offsetHeight;var head2Height = document.getElementById( "head2" ).offsetHeight; var mainH = buttonsHeight + head1Height +head2Height + 13; //20:scroll 35:title 25:tr while ((availHeight-mainH) < (20 + 35 + 25*index)*2){ index = index - 1;}var tableHeight = 20 + 35 + 25*index; document.getElementById( "TableContainer1" ).style.height = tableHeight + 'px'; document.getElementById( "TableContainer2" ).style.height = tableHeight + 'px'; window.resizeTo(document.body.offsetWidth,mainH + tableHeight*2);}
