| data | a data object, can either be dataframe or a matrix. |
|---|---|
| columns | a dataframe containing different column attributes. The row number of the dataframe specifies the column for which the attribute is to be specified and the header of the dataframe specifies the attribute, e.g., title, width, type, source, multiple, render, readOnly. |
| colHeaders | a vector of specifying the column headers. If both 'colHeaders' and 'title' attribute in columns is specified, the latter will take precedence. |
| rowHeight | a dataframe or matrix specifying height of different rows. The first column consists of numerical value that specifies the row number and the second column is also numerical value that specifies the height in pixels. |
| nestedHeaders | a list of dataframe having title and colspan as the attributes. The nested header in the same level should be in the same dataframe. |
| defaultColWidth | a numeric value specifying the default width of column when the width attribute of column is not specified. The default value is 50. |
| minDimensions | a vector that defines the minimum number of rows and columns in the tables irrespective of the size of data. The first parameter should be of number of columns followed by number of rows. If data is null then it will create an empty table with the given dimensions. |
| columnSorting | a boolean value indicating if column sorting should be enabled. When enabled double click on the table headers sorts the column. By default it is set to true. |
| columnDrag | a boolean value indicating if column dragging is enabled. By default it is set to false. |
| columnResize | a boolean value indicating if column resizing is enabled. By default it is set to true. |
| rowResize | a boolean value indicating if row resizing is enabled. By default it is set to false. |
| rowDrag | a boolean value indicating if rowDragging is enabled or not. By default it is set to true. |
| editable | a boolean value indicating if the table can be edited. By default it is set to true |
| allowInsertRow | a boolean value indicating if user is allowed to insert new rows. By default it is set to true. |
| allowInsertColumn | a boolean value indicating if user is allowed to insert a new column. By default it is set to true. |
| allowDeleteRow | a boolean value indicating if user is allowed to delete a row. By default it is set to true. |
| allowDeleteColumn | a boolean value indicating if user is allowed to delete a column. By default it is set to true. |
| allowRenameColumn | a boolean value indicating if user is allowed to rename the columns. By default it is set to true |
| allowComments | a boolean value indicating if commenting on cell should be enabled. By default it is set to false. |
| wordWrap | a boolean value indicating if words in the cells should wrap. By default it is set to false. |
| selectionCopy | a boolean value indicating if user is allowed to copy selected cells. By default it is set to true. |
| mergeCells | a list containing vector of colspan and rowspan respectively such that the tag of the list specifies the cell number. |
| search | a boolean value indicating if search should be enabled. By default it is set to false. |
| pagination | a numeric value indicating number of rows in a single page. If the data does not fit in a single page pagination is enabled. |
| fullscreen | a boolean value indicating if the table should be fullscreen. By default it is set to false. |
| lazyLoading | a boolean value indicating if lazy loading should be enabled. By default it is set to false. |
| loadingSpin | a boolean value indicating if loading spinner should be enabled. By default it is set to false. |
| style | a named list to specify style for each cell. The name should be the cell address and the value should be
a valid 'css' string with styles. For example, to style cell 'A1', the list should look like
'type' is not specified in 'columns' attribute
|
| autoColTypes | a boolean value indicating if column type should be automatically detected if |
| showToolbar | a boolean value indicating if toolbar should be shown. By default it is set to false. |
| dateFormat | a string value indicating the date format if column of type 'calendar' is present. By default the format is 'DD/MM/YYYY'. |
| digits | number of decimal digits passed to |
| autoWidth | a boolean value indicating should the width of the column be automatically adjusted. By default this value is set to TRUE. The width value specified in 'columns' param will have higher precedence. |
| autoFill | a boolen value indicating whether the excel table fill the container. By default this value is set to false. The width value specified in 'columns' param will have highest precendence followed by autoWidth. |
| getSelectedData | a boolean value indicating whether the there should be trigger for data selection or not. By default this is set to false. |
| ... | other jexcel parameters, e.g., updateTable |
