TPPDF表格数据版本2.3

Question

我一直在使用TPPDF来生成利用表格的pdf。使用旧版本，我可以按照下面的代码填充、设置对齐方式和样式。

_bodyData数组由String、String、UIImage as Any、String、UIImage as Any组成

static func addTextTableBody(_bodyData: [Array<Any>], _bodyAlign: [Array<PDFTableCellAlignment>], _bodyWidth: Array<CGFloat>, _bodyStyle: [Array<PDFTableCellStyle>], _colHeaderCount: Int, _colHeaderStyle: PDFTableCellStyle, _rowHeaderStyle: PDFTableCellStyle, _contentStyle: PDFTableCellStyle, _altContentStyle: PDFTableCellStyle, _outlineStyle: PDFLineStyle, _padding: CGFloat, formType: Int) ->PDFTable {
    let tableData = PDFTable()
    // Tables can contain Strings, Numbers, Images or nil, in case you need an empty cell. If you add a unknown content type, an error will be thrown and the rendering will stop.
    do {
        try tableData.generateCells(
        data: _bodyData,
        alignments: _bodyAlign)
    } catch PDFError.tableContentInvalid(let value) {
        // In case invalid input is provided, this error will be thrown.
        print("This type of object is not supported as table content: " + String(describing: (type(of: value))))
    } catch {
        // General error handling in case something goes wrong.
        print("Error while creating table: " + error.localizedDescription)
    }

    // The widths of each column is proportional to the total width, set by a value between 0.0 and 1.0, representing percentage.
    tableData.widths = _bodyWidth

    // To speed up table styling, use a default and change it
    let style = PDFTableStyleDefaults.simple
    style.columnHeaderStyle = _colHeaderStyle
    style.rowHeaderStyle = _colHeaderStyle

    style.contentStyle = _colHeaderStyle
    style.alternatingContentStyle = _colHeaderStyle

    style.columnHeaderCount = _colHeaderCount
    style.rowHeaderCount = 0
    style.footerCount = 0

    style.outline = _outlineStyle//PDFLineStyle(type: .full)
    tableData.style = style

    // Set table padding and margin
    tableData.padding = _padding
    tableData.margin = 0.0

    return tableData
}

在新版本中，我已经看到了像这样的例子，TPPDF Table Alignments如何将字符串、整数、图像混合到表数据中，当它显示表内容接受以下形式的数据时。

let tableData: [[String]] = [...] // This is your nested data

如果能帮上忙，我将不胜感激。

Answer 1

generateCells()的接口已经被弃用了一段时间，并在最近的更新中被删除。

相反，请看一下Table Example，它展示了如何使用更高级的API。下面是摘录：

var table = PDFTable(rows: 3, columns: 2)
table.content = [
    nil, "Name",
    1,   "Waterfall",
    2,   "Fireworks"
]
table.rows.allRowsAlignment = [.center, .left]
table.widths = [
   0.2, 0.8
]

我希望这会有所帮助，否则请仔细看看documentation。
