The table-layout property determines the algorithm used for sizing table columns. In fixed mode, column widths depend on explicit specifications (from the first row / colgroup) rather than content — faster to render for large tables.table {
table-layout: fixed;

width: 100%;
}autoThe default value. Column widths adjust based on content (automatic table layout algorithm).fixedUses only explicitly specified widths from the first row; content in subsequent rows is ignored for sizing.CSS Tables Module Level 3Working DraftW3CMDN
