Description

The TableAttribute is inherited to subclasses but then ignored by the CRUD operations. This is due to the method SQLMapperExtensions.GetTableName ignoring inherited CustomAttributes.

https://github.com/DapperLib/Dapper.Contrib/blob/cf24f6bdc577b1e071c3764ddfb2cf3382531405/src/Dapper.Contrib/SqlMapperExtensions.cs#L290-L293

This feels wrong since the attribute is actually being inherited and attributes on property level are not being ignored, e.g.: properties with ExplicitKeyAttribute

https://github.com/DapperLib/Dapper.Contrib/blob/cf24f6bdc577b1e071c3764ddfb2cf3382531405/src/Dapper.Contrib/SqlMapperExtensions.cs#L87-L98

Currently you have to either specify the table name for every subclass or make use of SQLMapperExtensions.TableMapper.
Is this behaviour wanted?

Research direction

Start in src/Dapper.Contrib/SqlMapperExtensions.cs at GetTableName and compare its CustomAttributes handling with the ExplicitKeyAttribute handling around the referenced lines. Verify how inherited TableAttribute values flow through CRUD operations and determine whether those operations should use the inherited table name rather than requiring TableMapper or repeated attributes.
