I would like to combine multiple tables of the same format (columns) into one large table so that I can run queries on the union of all the data.

For example:

Table1:

```
Product       Spec
AProduct 1    ASpec 1
AProduct 2    ASpec 2

```

Table 2:

```
Product      Spec
BProdcut 1   BSpec 1
BProduct 2   BSpec 2

```

Table 3:

```
Product      Spec
CProduct 1   CSpec 1
CProduct 2   CSpec 2

```

Want a large table to show:

```
Product      Spec
AProduct 1   ASpec 1
AProduct 2   ASpec 2
BProdcut 1   BSpec 1
BProduct 2   BSpec 2
CProduct 1   CSpec 1
CProduct 2   CSpec 2

```
