示例1:
export const filterTableColumns = (
data: string[][],
fieldOptions: FieldOption[]
): string[][] => {
const visibility = {}
const filteredData = fastMap<string[], string[]>(data, (row, i) => {
return fastFilter<string>(row, (col, j) => {
if (i === 0) {
const foundField = fieldOptions.find(
field => field.internalName === col
)
visibility[j] = foundField ? foundField.visible : true
}
return visibility[j]
})
})
return filteredData[0].length ? filteredData : [[]]
}
示例2: Set
export const sortTableData = (
data: string[][],
sort: SortOptions
): {sortedData: string[][]; sortedTimeVals: string[]} => {
const headerSet = new Set(data[0])
let sortIndex = 0
if (headerSet.has(sort.field)) {
sortIndex = _.indexOf(data[0], sort.field)
}
const dataValues = _.drop(data, 1)
const sortedData = [
data[0],
..._.orderBy<string[][]>(dataValues, sortIndex, [sort.direction]),
] as string[][]
const sortedTimeVals = fastMap<string[], string>(
sortedData,
(r: string[]): string => r[sortIndex]
)
return {sortedData, sortedTimeVals}
}
