# Tables Tables are what hold your measures ([dimension](/data-management/explorations/dimensions.md) & [metrics](/data-management/explorations/metrics.md)). They are based on a dataset that you have either [imported](/data-management/workbench/import-raw-data.md) or that you have [modeled](/data-management/workbench.md). They allow you to use the relationships that you have defined with all your models to add [related data](/data-management/explorations/tables/add-related-data.md) and create exploration that abstract the complexity of joins for your end users. An exploration must have at least one exploration. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.whaly.io/data-management/explorations/tables.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
