1、修改table表头:

div .ant-table-thead > tr > th{
	background: #EEF4FE;
	text-align: center;
	border-right: 0px !important;
        font-size:14px;
        font-weight: 400;
}

2、修改table行hover样式：

.ant-table-tbody > tr:hover:not(.ant-table-expanded-row):not(.ant-table-row-selected) > td {
    background: #2e88ed;
}
