A value of 'auto' (for both 'display: table' and 'display: - inline-table') means use the automatic table layout algorithm. - - In the fixed table layout algorithm, the width of each column is - determined as follows: - - 1. A column element with a value other than 'auto' for the 'width' - property sets the width for that column. - - 2. Otherwise, a cell in the first row with a value other than - 'auto' for the 'width' property sets the width for that column. If - the cell spans more than one column, the width is divided over the - columns. - - 3. Any remaining columns equally divide the remaining horizontal - table space (minus borders or cell spacing). - - The width of the table is then the greater of the value of the - 'width' property for the table element and the sum of the column - widths (plus cell spacing or borders). If the table is wider than - the columns, the extra space should be distributed over the columns. - - - In this manner, the user agent can begin to lay out the table once - the entire first row has been received.
