“材料表” - 如何为每页添加更多行并修复渲染 - ReactJs

Question

I am trying to apply more rows per page to my table from material-table . Until now i found out that you can add an array with with the wishful rows per page ex. rowsPerPageOptions={[5, 10, 25, 50, 100]} , but my problem is when i apply the row of 100 the table extends to an blank one . ( i receive at the moment only 24 rows (documents) from the backend ) So basicly it has to be limitted to the data that i have . Can some one give me a hand ? Thank you

 divideItems = () => {

        let startIndex = ((parseInt(this.state.activePaginationTab) + 1) * this.state.rowsPerPage) - this.state.rowsPerPage;
        let endIndex = (parseInt(this.state.activePaginationTab) + 1) * this.state.rowsPerPage - 1;
        let tabItems = [];

        for (let i = startIndex; i <= endIndex; i++) {
            if (this.state.items[i]) {
                tabItems.push(this.state.items[i]);
            }
        }


        this.setState({
            tabItems
        }, () => {

        });

    }
    getNewIndex = (event, page) => {
        this.setState({
            activePaginationTab: page
        }, () => { this.divideItems() })
        // this.divideItems(page)


    };

    handleChangeRowsPerPage = (event) => {

        this.setState({
            rowsPerPage: event.target.value
        }, () => {
            this.divideItems();
        })
    }

render() {
  components={{
              Pagination: props => (
                  <TablePagination
                      {...props}
                      rowsPerPageOptions={[5, 10, 25, 50,100]}
                      rowsPerPage={this.state.rowsPerPage}
                      count={this.state.items.length}
                      />
    ),

Answer 1

We can add rows per page and further pagination options as

   <MaterialTable
      title=""
      columns={myColumns}
      data={myData}      
      options={{
        paging:true,
        pageSize:6,       // make initial page size
        emptyRowsWhenPaging: true,   //to make page size fix in case of less data rows
        pageSizeOptions:[6,12,20,50],    // rows selection options
      }}
    />

Answer 2

如文档中所述，您可以使用 emptyRowsWhenPaging 并在选项中将其设置为 false。

Answer 3

Add these attribute in the options section of the material table

    pageSize:10
    pageSizeOptions:[10,20,30]

• PageSize: Number of rows that would be rendered on every page

• pageSizeOptions: Page size options that could be selected by user

   options={{ pageSize:10, pageSizeOptions:[10,20,30],

  }}
