这意味着点表中每一行的键值（在这个示例中，由两个列值组成）必须也在源表中存在。
This means that every row in the point table must have a key value (consisting, in this case, of two column values) that must also exist in the source table.
下一步，要计算您将需要使表居中的缩进量，这基于页面宽度、两个 72点边距、一个宽列和三个正常列。
Next, calculate the amount of indent you'll need to center the table, based on the page width, two 72-point margins, one wide column, and three regular columns.
要这样做，就使用未辨别的路径图符号表中的Value列的每一行中的Browse按钮（标记为省略号，或三个点），然后单击Refresh。
To do this, use the Browse button (which is labeled only with ellipses, or three dots) in each row of the Value column in the unresolved path map symbol table, and then click Refresh.
当更新源表中的坐标列时，必须构造一个新的点几何值。
When either of the coordinate columns in the source table is updated, a new point geometry must be constructed. The update trigger looks like this
空间表的结构很简单：一个惟一的整数列(objectid)，组成主键的一个或多个列(从源表复制的)，以及一个点几何列。
The spatial table has a simple structure: a unique, integer column (objectid), one or more columns making up the primary key (copied from the source table), plus a single point-geometry column.
这一点上Excel透视表非常的灵活，标签可以被放在行，列，或者那些区域层级的任意位置。
Excel PivotTables offer significant flexibility in this area - the labels can be on rows, on columns, and anywhere in the hierarchy on either of those areas.
