one simple solution if know every table have 8 columns in (like have in example code) can set header-table columns , body-table columns same widths align properly. in case 8 columns use width:12.5% each of columns same width. css code this:

.headertable th {      background-color: lightblue;      width:12.5%; } .bodytable td {      white-space: normal; /*text-overflow: ellipsis;*/      overflow: hidden;      word-spacing: normal;      font-family: sans-serif;      font-size: 14px;      text-align: right;      width:12.5%; }
