You can create a table heading cell that spans both columns . set the 您可以创建跨越两列的表标题单元格。
A folk dance performed in two lines with the partners facing each other 对舞一种由面对面排成两列的舞伴表演的民间舞蹈
For example , the following declaration creates a two - dimensional array of four rows and two columns 例如,下列声明创建一个四行两列的二维数组:
A two - column table is added to the page that takes up the entire height and width of the page 将包含两列的表格添加到页面中,占据页面的整个高度和宽度。
The following example creates a table with two columns and inserts a value into the first column , and the other column remains null . a 以下示例将创建一个包含两列的表,在第一列插入一个值,另一列保持为null 。
Interface . the list of schemas and restrictions are returned as a datatable with two columns named " schema " and " restrictionsupport " 架构和限制的列表可以作为具有名为“ schema ”和“ restrictionsupport ”的两列的datatable返回。
Moreover , the generalized hadamard product of two columns of an orthogonal array is extended to that of two orthogonal arrays , which makes the constructed arrays have more non - prime power level columns 推广正交表两列的广义hadamard积到正交表的广义hadamard积,使得所构造的混合水平正交表具有较多的非素数幂水平列。
Furthermore , if indexes already exist for both columns one for empno and one for deptno , db2 can use them both to satisfy this query so creating another index might not be necessary 而且,如果已经存在关于这两列的索引(一个关于empno ,一个关于deptno ) , db2可以使用它们来满足该查询,因此创建另一个索引也许是没有必要的。
And we provide a general approach to construction of mixed - level orthogonal arrays by using generalized hadamard product of two columns of an orthogonal array based on orthogonal decomposition of projection matrix ?作为投影矩阵的正交分解的一个应用,获得了构造正交表的分层方法的推广形式。研究了用正交表两列的广义hadamard积构造混合水平正交表的方法。
