# AnalyzeTable Method of the FRPage Object

This method replaces the specified block with the table block and analyzes the structure of the table.

## Syntax

### C++

```cpp theme={null}
HRESULT AnalyzeTable(
  int                       BlockIndex,
  IPageAnalysisParams*      AnalysisParams,
  IObjectsExtractionParams* ExtractionParams,
  IRecognizerParams*        RecognizerParams
);
```

### C\#

```csharp theme={null}
void AnalyzeTable(
  int                     BlockIndex,
  IPageAnalysisParams      AnalysisParams,
  IObjectsExtractionParams ExtractionParams,
  IRecognizerParams        RecognizerParams
);
```

### Visual Basic .NET

```vb theme={null}
Sub AnalyzeTable( _
  BlockIndex As Integer, _
  [AnalysisParams As IPageAnalysisParams = Nothing], _
  [ExtractionParams As IObjectsExtractionParams = Nothing], _
  [RecognizerParams As IRecognizerParams = Nothing] _
)
```

## Parameters

BlockIndex

\[in] Specifies the index of block in the collection of blocks which must be analyzed as table.

AnalysisParams

\[in] Refers to the [PageAnalysisParams](/fine-reader/engine/api-reference/parameter-objects/preprocessing-analysis-recognition-and-synthesis-parameters/pageanalysisparams) object that stores parameters of layout analysis of the table. This parameter may be 0. In this case, the table is analyzed with default parameters, or, if a [profile](/fine-reader/engine/guided-tour/advanced-techniques/working-with-profiles) has been loaded, the parameters set by this profile are used.

ExtractionParams

\[in] Refers to the [ObjectsExtractionParams](/fine-reader/engine/api-reference/parameter-objects/preprocessing-analysis-recognition-and-synthesis-parameters/objectsextractionparams) object that stores parameters of objects extraction. This parameter may be 0. In this case, the objects are extracted with default parameters, or, if a [profile](/fine-reader/engine/guided-tour/advanced-techniques/working-with-profiles) has been loaded, the parameters set by this profile are used.

RecognizerParams

\[in] Refers to the [RecognizerParams](/fine-reader/engine/api-reference/parameter-objects/preprocessing-analysis-recognition-and-synthesis-parameters/recognizerparams) object that stores recognition parameters necessary for analysis of the table (e.g., recognition language). This parameter may be 0. In this case, the default parameters are used, or, if a [profile](/fine-reader/engine/guided-tour/advanced-techniques/working-with-profiles) has been loaded, the parameters set by this profile are used.

## Return values

If layout analysis is interrupted by the user, this method will return E\_ABORT. It also returns the [standard return codes of ABBYY FineReader Engine functions](/fine-reader/engine/api-reference/return-codes).

## Remarks

* Table blocks always have rectangular regions; if the block was not rectangular, the new table block receives the region corresponding to bounding rectangle of the initial block.
* If the table structure cannot be analyzed, the [IFRPage::Layout](/fine-reader/engine/api-reference/document-related-objects/frpage#layout) subobject is not changed.
* This method may report events to the listeners attached to the IConnectionPointContainer interface of the [FRPage](/fine-reader/engine/api-reference/document-related-objects/frpage) object.
