## Functions

### e_table_model_column_count ()

    gint
    e_table_model_column_count (ETableModel *table_model);

table_model | The e-table-model to operate on |

#### Returns

the number of columns in the table model.

This function instructs the model to store the value in `data` in the the `table_model` at column `col` and row `row` . The `data` typically comes from one of the ECell rendering objects.

There should be an agreement between the Table Model and the user of this function about the data being stored. Typically it will be a pointer to a set of data, or a datum that fits inside a gpointer .

row | the row where the data will be stored in the model. |
value | the data to be stored. |

#### Parameters

### e_table_model_no_change ()

    void
    e_table_model_no_change (ETableModel *table_model);

Use this function to notify any views of this table model that the contents of the table model have changed. This will emit the signal "model_no_change" on the `table_model` object.

It is preferable to use the `e_table_model_row_changed()` and the `e_table_model_cell_changed()` to notify of smaller changes than to invalidate the entire model, as the views might have ways of caching the information they render from the model.

#### Parameters

table_model | the table model to notify of the lack of a change |

### e_table_model_changed ()

    void
    e_table_model_changed (ETableModel *table_model);

Use this function to notify any views of this table model that the contents of the table model have changed. This will emit the signal "model_changed" on the `table_model` object.

It is preferable to use the `e_table_model_row_changed()` and the `e_table_model_cell_changed()` to notify of smaller changes than to invalidate the entire model, as the views might have ways of caching the information they render from the model.

#### Parameters

table_model | the table model to notify of the change |

### e_table_model_row_changed ()

    void
    e_table_model_row_changed (ETableModel *table_model,
                               gint row);
